Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass
one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. Jupiter
and Saturn are gas giants; the other two giant planets, Uranus and Neptune are ice giants. Jupiter has been known to astronomers
since antiquity. The Romans named it after their god Jupiter. When viewed from Earth, Jupiter can reach an apparent
magnitude of −2.94, bright enough for its reflected light to cast shadows, and making it on average the third-brightest
object in the night sky after the Moon and Venus.
