The sun is a star, as the UV rays ruin our atmosphere at this range, it is doubtful stars have any, but stars are made entirely of gas which makes an atmosphere. Besides that, no one knows yet.
The least prominent gas in the atmosphere is xenon. It represents no more than one percent on the air in the atmosphere.
No. Mars has a rocky surface and a metallic core.
Venus is not made up of gas, but it does have a thick atmosphere. The main gas in the atmosphere is carbon dioxide, at about 96%. There's some nitrogen (about 3.5%) and traces of other things.
Basically the reason why the moon hasn't got a atmosphere its because there are no active/live volcanoes at all which means its a dead lump of rock which can't support any living things. Its a chunk of rock meteorites hit the moon all the time that it would destroy its atmosphere (if it had one) any ways. also to hold and atmosphere is would need Oxygen and Carbon Dioxide and all these types of gases for it to happen.
Oxygen makes up roughly 21% of our atmosphere. Nitrogen is the dominant gas in our atmosphere (roughly 78%). The remaining 1% is comprised of carbon dioxide and other trace gases.
Oxygen.
The number one gas in martian atmosphere is carbon dioxide.
No part of the atmosphere consists of one gas only.
The sun is a star, as the UV rays ruin our atmosphere at this range, it is doubtful stars have any, but stars are made entirely of gas which makes an atmosphere. Besides that, no one knows yet.
The Earth's atmosphere is composed of the following gasses:Oxygen (O2) - 21%Nitrogen (N2) - 78%Argon (Ar) - 1%Carbon Dioxide (CO2) - 0.038%Water (H20) - varies from 0 - 4%Neon (Ne) - 0.0018%Helium (He) - 0.000524%Methane (CH4) - 0.0002%Krypton (Kr) - 0.000114%Hydrogen (H2) - 0.00005%Nitrous oxide (N2O) - 0.00005%xenon (Xe) - 0.0000087%Thus, water vapour can make up as much as 4% of the Earth's atmosphere.
The least prominent gas in the atmosphere is xenon. It represents no more than one percent on the air in the atmosphere.
A gas that forms oxygen is ozone. It is the one present in the upper atmosphere.
The ozone gas is the important one in atmosphere. It is present inside the stratospheric region of atmosphere.
Ozone gas makes one important part of the atmosphere. It protects us from the deadly UV rays.
