  • Brown and colleagues say Planet Nine could have been cast off during the early formation of the solar system, when four major cores grabbed up the gas around them and formed Jupiter, Saturn, Uranus and Neptune. (yahoo.com)
  • He ran 1001 computer simulations of the solar system over time, each with slightly different starting conditions for the planets based on the range of uncertainties in the observations. (newscientist.com)
  • Historically, the solar system has been the key performer in the greatest and grandest show on earth, the drama of the sky with the sun moving across it each day and with the fixed stars of the constellations providing each night a slowly moving backdrop against which the more agile moon, and five visible planets-Mercury, Venus, Mars, Jupiter, and Saturn-performed their routines. (newworldencyclopedia.org)
  • Like much of Galileo's work, the observation that Venus has phases provided supporting evidence that the Earth is not the center of the universe, but instead revolves around the Sun with everything else contained in our Solar System. (skeptoid.com)
  • Venus is thought to be about 4.5 billion years old, roughly the age of the Solar System. (skeptoid.com)
  • Venus has more than 1,000 volcanoes on its surface that produce the longest lava flows in the Solar System, extending for hundreds of kilometers. (skeptoid.com)
  • In another, Mars was flung out of the solar system after 820 million years, then 40 million years later Mercury and Venus collided. (newscientist.com)
  • The view pulls back to reveal the outer fringes of the system and a ring of dusty debris that circles the star. (caltech.edu)
  • Total solar eclipses like this happen, on average, about once every 18 months, due to the frequency of alignment as well as the Moon's apparent angular size. (scienceblogs.com)
  • If Jupiter flung the lost ice giant from the solar system, it would have lost angular momentum and receded from the sun. (newscientist.com)
  • The result of this angular momentum transfer is that the gas giant closest to the star will spiral into that star, then the next gas giant in line spirals into the star, and so on, until the gas and crap in the solar system is blown out of the system by the star and this process stops. (slashdot.org)
  • All of the planets, including the earth are surrounded by a teardrop shaped magnetosphere generated by the interaction of the magnetic field of the solar wind with that of each planet. (newworldencyclopedia.org)
  • However, very little is known about the underlying interaction between the solar wind and a planet's magnetic field. (springer.com)
  • The planet does have a weak magnetic field, though, thought to be caused by the interaction between solar wind and the planet's atmosphere. (skeptoid.com)
  • For two years now, data beamed back to Earth by Voyager 1 has hinted at its close approach to the edge of the solar system , a pressure boundary called the heliopause. (yahoo.com)
  • Scientists had expected to see the solar wind veer sideways when it met the heliopause, like water hitting a wall, rather than screech to a halt. (yahoo.com)
  • In short, in late August, cosmic ray collisions sharply rose, and solar particle collisions sharply fell: two indicators of a transition through the heliopause. (yahoo.com)
  • Its findings could unlock the secrets of how Mercury formed, and help scientists to understand what our solar system was like at its very beginning. (popularmechanics.com)
  • This would tend to destabilise the whole inner solar system and could lead to a catastrophic collision between Earth and either Mercury or Mars, wiping out any life still present at that time. (newscientist.com)
  • For example, from meteorites we are familiar with the first centimetre-sized mineral aggregates in the solar system, but we know very little about how they formed. (innovations-report.com)
  • While the major planets lie within 40 Astronomical Units (AU) - the average distance of Earth to the Sun - the outermost boundary of the solar system stretches to 1 million AU, one-third the way to the nearest star. (encyclopedia.com)
  • These close encounters result in the loss of objects (essentially dormant cometary nuclei located in the outer Oort cloud ) that are on, or near, the boundary of the solar system. (encyclopedia.com)
  • Yet the solar system and its immediate outer boundary still represent the limit of our physical reach, and they remain the core of our theoretical understanding of the cosmos as well. (britannica.com)

  • This jumping Jupiter theory is very difficult to achieve for the four-planet system. (newscientist.com)
  • Its planets are Jupiter-sized and its discovery suggests that solar systems such as our own may be commonplace in the Universe. (slashdot.org)

  • During the heating season, the system is turned on and heated air collects in the pocket, and is sucked in through new duct work to the existing ventilation system. (unionleader.com)
  • One idea holds that the primordial soup of our solar system was not uniform, and that a high concentration of metals was rotating close to the sun, causing Mercury's composition to be primarily metal. (popularmechanics.com)
