all parts of the planet pulled each other toward the center of the mass by gravity
The atmosphere of Earth contains about 78.08% nitrogen. There has been no other place found that has this nitrogen in abundance, with Mars having only 3% as a remainder of its thin and low-pressure atmosphere.

The planet Earth has a sufficiently large mass, and correspondingly large gravitational field, to enable it to hold on to a large atmosphere.

An atmosphere is a gaseous layer that surrounds large planetary bodies. The gases of the atmosphere stay in place around the body because of its gravitational pull.
Earth is the only planet with a bountiful supply of water.
The inner planets are small rocky bodies, whereas the outer planets are gas giants, large balls of gas with ring systems and a large quantity of Moons.
