Jupiter is the fifth planet from the Sun and by far the largest. Jupiter is more than twice as massive as all the other planets combined (318 times Earth).

 orbit:    778,330,000 km (5.20 AU) from Sun
 diameter: 142,984 km

Jupiter is the fourth brightest object in the sky (after the Sun, the Moon and Venus; at some  times Mars is also brighter).

It has been known since prehistoric times.

Jupiter was first visited by Pioneer 10 in 1973 and later by Pioneer 11, Voyager 1, Voyager 2 and Ulysses.

 The Great Red Spot (GRS) has been seen by Earthly observers for more  than 300 years. It is an oval about 12,000 by 25,000 km, big  enough to hold two Earths!

 Jupiter has rings like Saturn's, but much fainter and smaller.

Jupiter has 16 known satellites, the four large Galilean moons and 12 small ones.
