Document Summary

Jupiter and saturn are composed almost entirely of hydrogen and helium, has no solid surface. Great red spot: a storm on jupiter that is a couple times the size of earth. Uranus and neptune are primarily made of hydrogen compounds, hydrogen, and helium. Uranus is tipped on its side, likely as a result from an extreme collision, which causes extreme seasonal variations. Great dark spot: large storm on neptune. Further planets took longer to form, and therefore captured less hydrogen and helium when the solar system cleared. Jupiter and saturn are nearly the same size, but jupiter is far more massive. This is because as you add mass, it compresses the material. 8. 2 a wealth of worlds: satellites of ice and rock. The most volcanically active world in our system. Tidal heating, ongoing processes in the interior heats the inside of the planet, Orbital resonance among the galilean moons makes io"s orbit slightly elliptical.
