YEAR 7 : PLANETS: Home

Planet is a large, round body that orbits a star and shines by the reflection of the star’s light. The International Astronomical Union (IAU), an organization of astronomers, recognizes eight planets that orbit the sun in our solar system. In order of increasing distance from the sun, they are (1) Mercury, (2) Venus, (3) Earth, (4) Mars, (5) Jupiter, (6) Saturn, (7) Uranus, and (8) Neptune. The IAU recognizes many smaller objects that also orbit the sun, with some such as Pluto and Ceres, designated as dwarf planets. In addition, astronomers have discovered thousands of extrasolar planets, (or exoplanets)—that is, planets that orbit other stars.
