Document Summary

Jovian planets can be roughly divided into 2 groups: Jupiter & saturn: similar in size (large, ~), with similar reddish and brownish color. Uranus & neptune: smaller in size (~4 ), with similar bluish color. Gas giants: no solid surfaces, no cratering (record of age, no tectonics or volcanology. Numerous moons: similar to terrestrial planets. When solar wind started and cleared planetary nebula. Density of saturn, uranus, and neptune indee increases as expected, but that of. Formed far from the sun, beyond frost line. From ice-rich planetesimals of about same mass, ~10. High mass & strong gravity allow them to draw in and hold onto large amounts of h and he gas. Icy component makes up larger fraction of mass for planets farther away from the sun. Density of jovian planets should increase the farther away the planet is from the sun, but not the case for jupiter.
