Ecliptic plane orbit. Medical search. Frequent questions

For Earth, the synodic day is not constant, and changes over the course of the year due to the eccentricity of Earth's orbit around the Sun and the axial tilt of the Earth. (wikipedia.org)
The odd term " eccentricity " when applied to ellipses and orbits is basically a measure of how far apart the two focal points are. (projectrho.com)
Beyond 50 AU, the main Kuiper belt appears to end, and what few objects have been discovered beyond this distance have all been on very high eccentricity (non-circular) orbits. (checktheevidence.com)
Most of these high-eccentricity orbits are the result of Neptune "flinging" the object outward by a gravitational slingshot. (checktheevidence.com)
The equation of time accounts for the effects of obliquity (the tilt of the earth's axis of rotation relative to the plane of the ecliptic) and the eccentricity of the earth's orbit. (homerenergy.com)
But the amount of sunlight striking the top of the earth's atmosphere varies over the year because the distance between the sun and the earth varies over the year due to the eccentricity of earth's orbit. (homerenergy.com)

The planets orbit the Sun in a counterclockwise direction as viewed from above the Sun's north pole, and the planets' orbits all are aligned to what astronomers call the ecliptic plane. (nasa.gov)
Morevoer, it was seen quickly that these 'planets' move all in the same plane, in a band of the sky we call the ecliptic, or the zodiac, which is divided in 13 constellations: the 12 'classical' zodiacal constellations, plus Ophiuchus, were planets spend in fact more time than in neighboring scorpion.

This simulated view from above the Solar System shows the orbits of Jupiter, Saturn, Uranus, Neptune, and Pluto (in green). (windows2universe.org)
They orbit out beyond Neptune , in the general neighborhood of Pluto. (windows2universe.org)
Kuiper Belt Objects are just part of larger group of Trans-Neptunian Objects (TNOs) that orbit further from the Sun than Neptune. (windows2universe.org)
Some have orbits that take them around the Sun twice for every three times Neptune orbits . (windows2universe.org)
Scarcely a month after Galle and d'Arrest first saw Neptune, British astronomer William Lassell spotted a satellite orbiting the planet and named it Triton. (ufrgs.br)
Nereid is only about 340 kilometers (210 miles) in diameter and is so far from Neptune that it requires 360 days to make one orbit -- only five days less than Earth takes to travel once around the Sun. (ufrgs.br)
Astronomers concluded that some material (perhaps like that of the rings of Saturn) orbits Neptune, and was responsible for occasional blockage of the star's light. (ufrgs.br)
For example, Pluto is rotating in 3/2 the time of Neptune because Neptune, with its large mass forces Pluto's orbit (and many other asteroids in the transneptunian belt) to be so. (spaceobs.com)
CANADA-FRANCE-HAWAII TELESCOPE NEWS RELEASE Posted: December 14, 2005 A team of astronomers working in Canada, France and the United States have discovered an unusual small body orbiting the Sun beyond Neptune, in the region astronomers call the Kuiper belt. (checktheevidence.com)
We immediately realized that the object was about twice as far as Neptune from the Sun and that its orbit was potentially nearly circular," said UBC professor Brett Gladman, who noticed the unusual nature of the object when determining its orbit, "but further observations were required. (checktheevidence.com)

An equatorial orbit is a non-inclined orbit with respect to Terra's equator ( i.e., the orbit has zero inclination to the equator, 180° inclination if retrograde ). (projectrho.com)
An inclined orbit is any orbit that does not have zero inclination to the plane or reference (usually the equator). (projectrho.com)
The comet is on a prograde, half a million year orbit with a high 57 degree inclination relative to the ecliptic plane. (universetoday.com)
Also, the orbit of the moon and the obliquity of the ecliptic (likewise the inclination of the earth) should coincide, and they do not. (creation.com)
The mass, and the inclination of the orbit. (spaceobs.com)

Tides, primarily influenced by changes in the moon's orbit, are the main force behind this mixing, which has the potential to cool the climate. (judithcurry.com)
The Moon's orbit is tilted by 5° relative to the Earth's orbital plane, also known as the ecliptic. (judithcurry.com)
The points where the Moon's orbit intersects the ecliptic are called nodes. (judithcurry.com)
However, the Moon's orbital plane around the Earth undergoes a gradual precession that causes one of the nodes to complete a full rotation relative to one of the equinoxes over a span of 18.61 years. (judithcurry.com)
As a result of this precession, the 5° tilt of the Moon's orbit is either added to or subtracted from the Earth's axial tilt, resulting in a change in the Moon's declination (its position relative to the equator). (judithcurry.com)

The Earth's axis is tilted approximately 23.4 degrees off the ecliptic plane. (everything-everywhere.com)
The earth, if you remember your high school basics, rotates at a tilt of 23.5 degrees relative to the ecliptic plane. (kcrw.com)
The team is in the project's homestretch, sampling the night sky in the northern and southern hemispheres in a band of sky that reaches seven degrees above and below the ecliptic - an imaginary path traced by the sun and the planets as they move across the sky. (csmonitor.com)
In comes Planet X, in an essentially straight line Passage through the solar system altered only by its reaction to the sweeping arms, a jump each time nudging it into its retrograde orbit, and its avoidance of the Ecliptic backwash by diving below the Ecliptic to 32 Degrees below the Earth s Ecliptic plane. (zetatalk.com)
Complicating the problem, the object's orbit also has an extreme tilt, being inclined (tilted) at 47 degrees to the rest of the Solar System. (checktheevidence.com)
Measurement of Buffy's new position proved that the orbit was not only extremely tilted, inclined (tilted) at 47 degrees to the plane of the planetary system (essentially tying the record for a Kuiper belt object) but confirmed that Buffy was unlike any other previously-known object because it was on a nearly circular orbit while at a very large distance. (checktheevidence.com)

Certain spacecraft orbits, Sun-synchronous orbits, have orbital periods that are a fraction of a synodic day. (wikipedia.org)
Due to Mercury's slow rotational speed and fast orbit around the Sun, its synodic rotation period of 176 Earth days is three times longer than its sidereal rotational period (sidereal day) and twice as long as its orbital period. (wikipedia.org)
Such an orbit is generally used for military spy satellites, weather satellites, orbital bombardment weapons , and Google Earth . (projectrho.com)
Under the gentle thrust of its ion propulsion system, the spacecraft completed 18 revolutions of Vesta, the loops getting tighter and faster as the orbital altitude gradually decreased, until it arrived at its new orbit on schedule on September 18. (planetary.org)
In this mode the simulation illustrates the parallax caused by Earth's orbit around the Sun. Now the observer moves along Earth's orbital path (shown as a blue circle with the orange Sun in the center). (compadre.org)
Kepler's three laws describe how planetary bodies orbit the Sun. They describe how (1) planets move in elliptical orbits with the Sun as a focus, (2) a planet covers the same area of space in the same amount of time no matter where it is in its orbit, and (3) a planet's orbital period is proportional to the size of its orbit (its semi-major axis). (nasa.gov)
We 'see' the ecliptic arc across our sky because of Earth's tilt, but what this is in reality is the orbital planes of all the planets about our Sun . (astronomyonline.org)

NASA's MESSENGER spacecraft entered a permanent orbit around Mercury in 2011, and continues to return some outstanding science. (universetoday.com)

On December 11, 2010, Steve Larson of the Catalina Sky Survey noticed an odd brightness from Scheila, an asteroid on the outer region of the main belt of asteroids that orbit in an area between Mars and Jupiter. (astronomy.com)
Planets are confined to this plane, while asteroids can have quite high inclinations compared to this plane. (spaceobs.com)
Said otherwise all asteroids which have an orbit larger than 6 times the sun to earth distance. (spaceobs.com)

We have seen before that bodies travel at higher velocities in lower-altitude orbits, where the force of gravity is greater. (planetary.org)
But since the moon and planets move in orbits, whose planes do not differ greatly from that of the Earth's orbit, these bodies, when visible in our sky, always stay relatively close to the ecliptic line. (space.com)
Irregular, rocky bodies that orbit the Sun, mostly between the orbits of Mars and Jupiter. (flashnews.net)

These frigid balls of ice and rock, similar in location and size to the planet Pluto , orbit the Sun in a distant region called the Kuiper Belt. (windows2universe.org)
They typically take a couple of centuries to complete each orbit around the Sun. KBOs are large balls of ice and rock, similar in composition to Pluto and its largest moon Charon . (windows2universe.org)
Pluto is a frigid ball of ice and rock that orbits far from the Sun on the frozen fringes of our Solar System. (windows2universe.org)
In 1930, Clyde Tombaugh discovered Pluto after carefully photographing the night sky along the ecliptic for a year. (csmonitor.com)
This Titan flyby, however, took Voyager 1 below the south pole of Saturn and then north of the ecliptic (the plane of the solar system, which contains the planets - and famously, not Pluto - as they orbit the sun). (discovermagazine.com)

As viewed from Earth during the year, the Sun appears to slowly drift along an imaginary path coplanar with Earth's orbit, known as the ecliptic, on a spherical background of seemingly fixed stars. (wikipedia.org)
This is the plane which is the average location of the Earth's orbit. (everything-everywhere.com)
Technically, the ecliptic represents the extension or projection of the plane of the Earth's orbit out towards the sky. (space.com)
For example, the plane of Earth's orbit, the ecliptic, shows up as an enhancement even though SkyView isn't intended for viewing solar system objects. (sciencedaily.com)
Also, the earth's orbit in not a perfect circle. (kcrw.com)
Note: to keep the simulation simple it is assumed that Earth's equator is aligned with the ecliptic plane (the plane of Earth's orbit). (compadre.org)
Seasonal and latitude changes will effect where this arc appears - seasonal changes because of the lower in the winter, higher in the summer changes due to Earth's orbit about the Sun (more on this in the Earth section). (astronomyonline.org)

To the naked eye it also appears like the center of the secondary object's orbit is the center of the primary object, but this too is wrong. (projectrho.com)

KBOs generally orbit near the ecliptic plane in which the planets move. (windows2universe.org)

If the perigee is less than 2,000 km it is called a " highly elliptical orbit . (projectrho.com)
A recently-discovered dwarf planet, named Sedna, has an extra-long and usual elliptical orbit around the Sun. Sedna is one of the most distant objects yet observed, with an orbit ranging between 76 and 975 AU (where 1 AU is the distance between the Earth and the Sun). Sedna's orbit is estimated to last between 10.5 to 12 thousand years. (space.com)
Over the course of the 10-year mission, Solar Orbiter's highly elliptical orbit will get progressively more inclined to the ecliptic plane. (copernicus.org)
LISA/eLISA consists of three spacecrafts (Fig. 1), each individually following a slightly elliptical orbit around the Sun, trailing the Earth by about 20 degree. (2physics.com)

There was some time pressure to undertake such a mission - thanks to its highly eccentric orbit and its position along it, planetary scientists were concerned that Pluto's atmosphere would "freeze out" and snow down to the surface as it moved away from the sun, possibly as early as 2010. (discovermagazine.com)
Circling along its highly eccentric orbit around the Sun, Solar Orbiter provides both imaging and in-situ measurements of our star from viewpoints that are not Earth-based, allowing for novel science and novel techniques to be developed. (mpg.de)

KBOs are difficult to detect because their extreme distance makes them appear quite small and dim, and because they move so slowly along their orbits. (windows2universe.org)
The orbits of Oort Cloud objects can have arbitrary tilts, so the objects are scattered in a spherical distribution around the Sun, unlike the "doughnut shaped" distribution of KBOs. (windows2universe.org)
The orbits of KBOs may help us understand whether and how the orbits of the gas and ice giant planets may have evolved over our planetary system's lifetime. (windows2universe.org)
Today, roughly half of the 1,000 known KBOs have been discovered by Millis and his team in a project known as the Deep Ecliptic Survey. (csmonitor.com)

Pretty much all natural orbits are ellipses , though many look like circles to the naked eye (that was Kepler's valuable contribution to rocket flight). (projectrho.com)
After much struggling, Kepler was forced to an eventual realization that the orbits of the planets are not circles, but were instead the elongated or flattened circles that geometers call ellipses, and the particular difficulties Brahe hand with the movement of Mars were due to the fact that its orbit was the most elliptical of the planets for which Brahe had extensive data. (nasa.gov)
Since the orbits of the planets are ellipses, let us review three basic properties of ellipses. (nasa.gov)

Similarly, satellites in close orbits around Earth, such as the International Space Station, race around faster than the much more distant Moon. (planetary.org)
All of the naked eye planets - and the moon as well - closely follow an imaginary line in the sky called the ecliptic . (space.com)
Another theory Samec deals with is that the moon was captured by the earth as it passed by in an earth-crossing orbit. (creation.com)
Even if this unlikely event took place," Samec said, "the moon would likely have swung by in a parabolic or an elliptical trajectory, rather than the near-circular orbit of the present day moon. (creation.com)
As a result of the Moon orbiting the Earth in the same direction as the Earth's axial rotation, it takes 24.84 hours for the Moon to be over the same position, so there is a semidiurnal tide every 12.42 hours. (judithcurry.com)
Explorations of Neptune's moon Triton required a significant course correction for Voyager 2, and this also resulted in the probe trajectory moving out of (in this case below) the plane of the solar system. (discovermagazine.com)
A few years later, while orbiting the Moon in the Apollo 17 Command Module, mission commander Gene Cernan looked out the window just before sunrise and saw an awesome vista - a spectacular set of "streamers" radiating above the limb of the Moon. (smithsonianmag.com)

The zodiacal light is sunlight reflected by dust particles orbiting in the plane of the ecliptic in our solar system. (allthesky.com)
A second influence is the Ecliptic plane backwash of particles, returning to the Sun at its middle such that the planets are drawn in by gravity but held out by the Repulsion Force , thus caught bobbling about in the Ecliptic backwash while swept along by the sweeping arms. (zetatalk.com)

Landmarks on Dawn's voyage After leaving Earth, Dawn flew past Mars to the giant protoplanet Vesta, where it spent 14 months in orbit. (planetary.org)
He set Kepler, the task of understanding the orbit of the planet Mars, the movement of which fit problematically into the universe as described by Aristotle and Ptolemy. (nasa.gov)
But the reason Mars' orbit was problematic was because the Copernican system incorrectly assumed the orbits of the planets to be circular. (nasa.gov)
Plane' on the other hand is planis (like in Chrysia planitia on Mars). (spaceobs.com)

The Earth is held in its orbit by numerous forces, only one of which is the Sweeping Arms of the Sun which whisk the planets in a counterclockwise orbit around the Sun s middle. (zetatalk.com)

I am absolutely certain that he describes Venus before it entered the orbit that we know today. (bibliotecapleyades.net)

Thus, the gravity of the Sun pulls Planet X forward, up toward the Earth s Ecliptic plane which it cannot avoid as the Sun lies at the center of this Ecliptic plane, while held away from the Sun by the Repulsion Force so it moves slowly toward the Sun, and in a slight retrograde orbit as a result of the influence of the sweeping arms.
