This allowed them to keep their lighter gasses, plus their accumulated the gasses that blew off the inner planets - resulting in thick atmospheres. Because the inner planets are close to the sun, they are hotter. This caused their lighter gasses (like H & He) to boil off & blow away, resulting in thin atmospheres. Because the inner planets are close to the sun, they are hotter. This caused their lighter gasses (like H & He) to boil off & blow away, resulting in thin atmospheres. Once they have pulled themselves into a spherical shape and have cleared their path of all orbiting debris, they have completed formation. As Planetismals continue to orbit and collide with material as they go around the sun they eventually become big enough to have their own gravity & they begin pulling even continue more material in and and collide grow quickly.
