The Largest Planet
Jupiter is the largest planet in the solar system. It is so large that all of the other planets in the solar system could fit inside of it.
Jupiter is a large gas planet whose clouds change colours daily. 
A day on Jupiter lasts only 9 hours and 55 minutes.
This planet is made mostly of hydrogen and helium gases. 
Jupiter gives off two times more heat than it gets from the Sun. It shines very brightly in the night sky for nine months of the year when it is closest to Earth.
Jupiter has sixteen known moons. One of Jupiter's moons, Io, has active volcanoes on it.
