Jupiter is the 4th brightest object in sky, after the sun, moon, and Venus. Unlike Earth, Jupiter has 67 moons and 4 large moons; lo, Europa, Ganymede, and Callisto. Jupiter is 90% hydrogen and 10% helium. The vivid colors seen in Jupiter's clouds are the result of subtle chemical reactions. Jupiter also has a really cool spot on it called The Great Red Spot. The GRS is oval 12,000 by 25,000 km that's big enough to hold two earths.
Jupiter's enormous magnetic field is nearly 20,000 times as powerful as Earth's. And did you know that Jupiter was named after the Roman kind of gods? Also it would take 317 Earths to equal the mas of Jupiter! Jupiter has the shortest days of all eight days, Jupiter rotates on its axis every 9 hours or 55 minutes. One orbit of the sun takes Jupiter 11.86 Earth days.
