Jupiter is the largest planet in the solar system.
Because the orbit of Jupiter is outside the Earth's, the phase angle of Jupiter as viewed from the Earth never exceeds 11.5°.
Jupiter has the fastest orbit of all the planets, just 10 Earth hours to complete a whole run.
A huge violent hurricane blows non-stop around Jupiter called the Great Red Spot. Three or four Earths could fit inside it.
The Galilean Moons are the biggest moons on Jupiter, discovered by astronomer Galileo Galilei, which includes Io, Callisto, Europa and Ganymede. Ganymede is the largest moon in the solar system, even bigger than the planet Mercury.
