Yes, gravity does stop gases from escaping from the planet. This layer of gases is called the atmosphere and it allows humans and plants to survive.
The gases come together due to gravity and form a nebula which further form a star. it alo come sfrom
Gravity, which pulls an object inward, and inertia, which resists gravity. They combine to form a more-or-less circular orbit.
The Earth's atmosphere is made mainly of nitrogen(78%) and oxygen(21%) and small amount of argon(0.93%) and CO2 (0.03%) and other gases(0.04%)
Gravity compresses gases at the center of a solar nebula until temperatures are high enough for nuclear fusion to occur.
Our planet is the perfect distance from our sun to receive enough light to keep water in a liquid form, our atmosphere has a well balanced amount of Nitrogen, Oxygen, Carbon Dioxide and other gases to support life and trap heat within the planet. Our planet also has water, a very important 'ingredient' for life. It is also a 'rock' planet not a gas planet and has a strong enough gravitation pull to hold on to our atmosphere, without this gravity the gases in our atmosphere would drift into space. Which is why Mars's atmosphere contains a very little amount of Oxygen, it when into space over millions of years. All other planets we have seen in our galaxy do not have the requirements for life, they are either too hot, too cold, too toxic, etc. And the odds of a planet meeting these requirements are astronomical.
we can show that gases are dissolved in water by showing the gas escaping in the form of bubbles.
The sun's rays (ultraviolet radiation) come through the atmosphere and warm the surface of the earth. This warmth rises in the form of infrared radiation into the atmosphere, where it is trapped by greenhouse gases. These are gases like carbon dioxide, methane and water vapour. The warmed gases spread the heat around and prevent it escaping into space. This is how global warming is warming the planet.
Force of gravity is what keeps the planets form colliding.
Asteroids are too small to have enough gravity to prevent any atmosphere form escaping.
jupeters gravity disrupted their formation
Jupiter's gravity kept planetesimals from accreting
There certainly is enough material in the asteroid belt to form another planet, however the immense gravity of Jupiter prevented a planet from forming.

scientists theorize that it was jupiters gravity that kept it from forming
It is called a 'proto-planet', this is the 'before-planet'-stage; It has gathered enough mass to form a large gravity field and cause a spherical shape.
