Document Summary

All have rocky cores and are surrounded by hydrogen and helium gasses. You"re seeing high-velocity winds on jupiter kicking up gases. No surface to access; almost all atmosphere. Nasa"s juno mission is currently in orbit around jupiter. Huge amounts of gas (mostly hydrogen and helium) with a small rocky core. 95% hydrogen and helium, 5% rocky core. Rotation and winds in the upper atmosphere of jupiter dominate what we see from. Giant red spot is a hurricane=like storm. Outer planets have big atmospheres because as it gets colder, gasses slow down and create atmospheres on nearly anything with mass. Four biggest were discovered by galileo and are called the galilean moons. Largest moon in solar system; 3 times bigger than our moon. Clearly more cratering; surface isn"t being changed. Jupiter is so big, it is constantly capturing extra-terrestrial objects (currently over. If you have more moons, it is easier to catch even more.
