Jupiter is the fifth and largest planet in our solar system. This gas Jupiter is the fifth and largest planet in our solar system. This gas giant has a thick atmosphere and a dark, barely-visible ring giant has a thick atmosphere and a dark, barely-visible ring composed of dust from nearby meteoroids. Its most prominent composed of dust from nearby meteoroids. Its most prominent features are bands across its latitudes and a great red spot (which is features are bands across its latitudes and a great red spot (which is a storm).a storm).

Jupiter is a gaseous planet; it does not have a solid surface like the Jupiter is a gaseous planet; it does not have a solid surface like the Earth does (but probably has a solid, rocky core 10 to 15 times the Earth does (but probably has a solid, rocky core 10 to 15 times the mass of the Earth). When we look at Jupiter, we are seeing icy mass of the Earth). When we look at Jupiter, we are seeing icy clouds of gases moving at high speeds in the atmosphere. The clouds of gases moving at high speeds in the atmosphere. The surface temperature of the highest clouds is approximately -153surface temperature of the highest clouds is approximately -153°C. °C. Jupiter's atmosphere is composed of about 90% Jupiter's atmosphere is composed of about 90% hydrogenhydrogen and 10 % and 10 % heliumhelium..
