Jupiter is the largest planet in our Solar System. It is the 5th planet away from the sun. It is like a star but it never started burning (It is not a failed star). There are A LOT of clouds on Jupiter. Since there are a lot of clouds in Jupiter, there are many storms present. A popular storm is the Great Red Spot. It has been around for hundreds of years! Jupiter is in fact a gas giant. It doesn't have a solid surface like the past 4 planets, but it could have a solid inner core the size of Earth! A year in Jupiter is quite a lot, It is about 4,333 Earth days which is 11.9 YEARS of Earth years. Jupiter also has a lot of moons it has about 79 of them. Three of them are, Io, Europa, And Ganymede (about a bit bigger than Saturn's popular moon Titan). Jupiter had not been discovered until 1610 and the discoverer is Galileo Galilei. He discovered a lot of planets that you know today. Jupiter as some special rain, Jupiter has diamond rain - its a bit of a theory (or not) - but it can have diamond rain! Now how was Jupiter named ''Jupiter?" Well a long time ago there was a king of Roman gods the kings name was Jupiter so they named this planet after this king of gods. Jupiter's mass is quite a lot if you take all the planets in the solar system and times it by 2 & 1/2 you still don't get Jupiter's mass! Now Jupiter and the satellites: The first satellite that went to Jupiter was Pioneer 1 and at the closest it got from Jupiter was in 1973. The satellites that have mostly seen Jupiter are Pioneer, Voyager, Ulysses, Cassini, New Horizons, Galileo, and Juno.
