Gravity on Jupiter: Jupiter is the largest and most massive planet in the Solar System. Its mean radius, at 69,911 Â± 6 km, makes it 10.97 the times the size of Earth, while its mass (1.8986Ã1027 kg) is the equivalent of 317.8 Earths.
Even in our Solar System, some accretion is still happening in different parts of the system. Check out this artistic rendition of nebular theory. Notice the general collection of matter in the middle (around the star, which has the most gravity because it is largest) and the large chunk of matter colliding into the newly forming planet in the matter.
