  1. planet
    (astronomy) any of the nine large celestial bodies in the solar system that revolve around the sun and shine by reflected light; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto in order of their proximity to the sun; viewed from the constellation Hercules, all the planets rotate around the sun in a counterclockwise direction
    A planet (from Greek πλανήτης, alternative form of πλάνης "wanderer") is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has clear
  2. solar system
    the sun with the celestial bodies that revolve around it in its gravitational field
    In 2006, the International Astronomical Union officially adopted a resolution defining planets within the Solar System.
  3. ice cap
    a mass of ice and snow that permanently covers a large area of land (e.g., the polar regions or a mountain peak)
    As observational tools improved, astronomers saw that, like Earth, the planets rotated around tilted axes, and some share such features as ice-caps and seasons.
  4. celestial body
    natural objects visible in the sky
    A planet (from Greek πλανήτης, alternative form of πλάνης "wanderer") is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has clear
  5. orbit
    the (usually elliptical) path described by one celestial body in its revolution about another
    A planet (from Greek πλανήτης, alternative form of πλάνης "wanderer") is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has clear
  6. solar
    relating to or derived from the sun or utilizing the energies of the sun
    In 2006, the International Astronomical Union officially adopted a resolution defining planets within the Solar System.
  7. Jupiter
    (Roman mythology) supreme god of Romans; counterpart of Greek Zeus
    In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune.
  8. galaxy
    (astronomy) a collection of star systems; any of the billions of systems each having many stars and nebulae and dust
    Since 1992, hundreds of planets around other stars ("extrasolar planets" or "exoplanets") in the Milky Way Galaxy have been discovered.
  9. Saturn
    (Roman mythology) god of agriculture and vegetation; counterpart of Greek Cronus
    In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune.
  10. Mercury
    (Roman mythology) messenger of Jupiter and god of commerce; counterpart of Greek Hermes
    In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune.
  11. Venus
    the second nearest planet to the sun; it is peculiar in that its rotation is slow and retrograde (in the opposite sense of the Earth and all other planets except Uranus); it is visible from Earth as an early `morning star' or an `evening star'
    In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune.
  12. Mars
    (Roman mythology) Roman god of war and agriculture; father of Romulus and Remus; counterpart of Greek Ares
    In order of increasing distance from the Sun, they are the four terrestrials, Mercury, Venus, Earth, and Mars, then the four gas giants, Jupiter, Saturn, Uranus, and Neptune.
