Mercury has no atmosphere due to its small size and due to the fact it is close to the sun, which has effectively 'burned' off any atmosphere that it may have had.

How does Saturn atmosphere affect the planet?

The atmosphere affects Saturn in many ways. One way that it affects it is because it affects the wind variations on the planet. Another way that it affects the planet is that it cause the "Green House Effect". The "Green House Effect" is when heat is trapped in something. If you think of a green house it is all glass to let is heat but not let the heat out. With a planet the planet gets heat from the sun and then when the planet starts to cool off the atmosphere holds the heat in. That is how an atmosphere can effect the planet.


How would the depth of an atmosphere change if a planet warms up or cools off?

If a planet warms up, the atmosphere would likely expand as the air molecules gain energy and move more vigorously, causing the atmosphere to become thicker. Conversely, if a planet cools off, the atmosphere would likely contract as the air molecules lose energy and slow down, causing the atmosphere to become thinner.


Why is it that planet earth is called the blue planet?

Planet Earth is called the blue planet because when viewed from space, its oceans and atmosphere make it appear predominantly blue in color. The reflection of sunlight off the water gives Earth its distinct blue hue when seen from afar.


Is there magnetism on every planet?

No. Mars has no magnetic field. Which is probably why it has no atmosphere either. The magnetosphere protects us from the solar radiation, which would otherwise knock our atmosphere off.


Which form of radiation given off by the earth causes heating of the earth's atmosphere?

Infrared radiation is the form of radiation given off by the Earth that causes heating of the Earth's atmosphere. This radiation is absorbed by greenhouse gases in the atmosphere, which traps heat and warms the planet.

Planet has almost no atmosphere?

The lack of atmosphere on a planet can result in extreme temperature variations between day and night, as well as high levels of radiation from the sun. Without an atmosphere to trap heat, temperatures can drop drastically at night. Additionally, the absence of atmospheric pressure can make it difficult for liquid water to exist on the planet's surface.


Explain how earth's mass is related to its ability to have an atmosphere?

The Earth has an atmosphere because it has the gravity necessary to keep the gases from floating off into space. The more mass a planet has, the more gravity it has, and the more gravity it has, the thicker an atmosphere it can sustain.


What planet doesn't have enough gravity to have an atmosphere?

Mercury - the closest planet to the sun. Solar wind and radiation from the sun also blast off some of Mercury's minuscule atmosphere (Mercury's atmosphere is sometimes referred to as an exosphere)

What keeps the atmosphere around the earth?

A magnetic field holds atmosphere to the planet. Without a magnetosphere the solar wind from the sun will blow the atmosphere away. That is why our planet still has an atmosphere, we have the magnetic poles.


Will a person be sucked up by the atmosphere on planet mars?

No. You cannot simply be "sucked up" by the atmosphere of a planet unless there just happens to be a storm with an extremely powerful updraft. Mars does have dust devils, but the atmosphere there is too thin for them to lift a person off the ground.
