Gas particles (atoms, molecules) composing the atmosphere of a planet have a mass, therefore they are trapped by the gravitational field of the planet. This is not only true for giant planets but applies to all planets with atmosphere.
What else can I help you with?
Why doesnt the gas on a gas giant planet escape into space?
For the same reason that our atmosphere on Earth does not escape into space - gravity.
Why doesnt the gas on a gas giant escape into space as it have on mercury?
because the gravity keeps the giants planets' gases from escaping.
Why doesnt the gas on a gas giant escape into space as it on mercury?
because the gravity keeps the giants planets' gases from escaping.
How do astronauts travel in space and escape earths atmosphere?
Astronauts travel in space and escape earth's atmosphere by wearing gravity resistant suits and traveling to outer space in a space shuttle that is insulated against the elements.
What layer of the atmosphere do particles of air escape into space?
The layer of the atmosphere that releases particles of air into space is the exosphere.
Why can't the atmospheres of the gas giants just escape into space?
Gravity.
Do meteorites have atmosphere?
No. Any atmosphere would quickly escape into space, due to the low gravity.
Atmosphere with hydrogen and helium?
An atmosphere composed mainly of hydrogen and helium would likely be very thin and lightweight compared to Earth's atmosphere. These gases are light and tend to escape easily into space due to the planet's gravity. Such an atmosphere might be similar to that of gas giants like Jupiter and Saturn.
The segment of the atmosphere which blends into interplanetary space is called?
The segment of the atmosphere that blends into interplanetary space is known as the exosphere. It is the outermost layer of Earth's atmosphere where the gas molecules are further apart and can escape into space. The exosphere is where the Earth's atmosphere merges with the vacuum of space.
There is no atmosphere on the moon. Explain on the basis of escape velocity?
The moon's escape velocity is lower than the average velocity of gas particles in its atmosphere, so the moon cannot retain an atmosphere as the gas particles would escape into space. This is why the moon has no significant atmosphere.
What keeps a gas giants atmosphere from esecaping into space?
The strong gravitational pull of the planet.
Why cant the atmospheres of gas giant escape into space?
gravity keeps the giants planet's gasas from escaping
