• Uranus
  • He then looked at data for all planets detected - terrestrials (Earth-sized), ice giants (like Uranus and Neptune), and gas giants (like Jupiter), getting their size and orbital period. (discovermagazine.com)
  • orbit
  • Imagine Spitzer has its infrared eye trained on a nearby star with a planet in orbit around it. (amnh.org)
  • For example, you see very few planets very close to the star (probably because it's hard to form or get a planet to orbit that close in), then more as you get farther out, then fewer at some large distance (which may, once again, simply be due to the fact that planets with long orbital periods can't be seen in the short duration of the data).

  • graduate student
  • In 1995, University of Geneva astronomer Michel Mayor and his graduate student Didier Queloz detected the first planet orbiting a star other than the Sun. Since then, this exciting new field of astronomy has exploded. (amnh.org)
