Jupiter has over 64 moons and its atmosphere is composed of clouds of dust, hydrogen, helium, water and ammonia. Jupiter is the fifth planet from the sun and gets as close as 370 million miles away. In ancient times, Jupiter was named after the king of the Roman gods. Some key facts about Jupiter are that the Great Red Spot is a massive storm twice the size of Earth that has raged for over 300 years, and Jupiter appears in different colors when viewed through a telescope because we only see its cloud tops.
