The planet's gravity.
gravity keeps the giants planet's gasas from escaping
The planet's strong force of gravity holds the atmosphere down and stops it escaping. Atmospheric gases have masses, and the Earth's atmosphere has a mass of about 1.2 kg per cubic metre.
Gravity is what keeps gases on Earth. The planet's gravitational force pulls gas molecules towards the surface, preventing them from escaping into space. The stronger the force of gravity, the more likely gases are to remain in the atmosphere.
Gravity is what keeps oxygen (and other gases) from escaping Earth's atmosphere. The gravitational force of Earth is strong enough to hold on to gases in its atmosphere, including oxygen. This allows for the maintenance of a stable and breathable atmosphere on the planet.

what keeps planet earth from fallin out of the sky
Insulation and reflection.
When an atmosphere keeps a planet warm, it's called the greenhouse effect. This phenomenon occurs when certain gases in the atmosphere, such as carbon dioxide and methane, trap heat from the sun, preventing it from escaping back into space. This process helps to maintain a stable and habitable temperature on the planet's surface. However, an excess of these greenhouse gases can lead to global warming and climate change.
It keeps the sun's warmth from escaping by the greenhouse effect
This is true. The greenhouse effect on earth holds back heat escaping from the earth.
