How were gas planets formed
WebThe Giant Planets. The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium. On Earth, both hydrogen and helium are gases, so Jupiter and Saturn are sometimes called gas planets. WebWithin this swirling debris, rocky particles began to collide, forming larger masses that soon attracted even more particles via gravity. These particles contracted under gravity to create planetesimals, which collided with one …
