Atmospheres are ball-shaped aggregates of gaseous molecules that are bound to a heavenly body (like Earth) by gravity. That definition means that there is no such thing as an atmosphere in the solar system at large.
There is a scattering of light moleules . . . hydrogen, maybe helium, but they are far, far apart from each other.
earth has people in it's atmosphere
the composition of Europa's atmosphere is mostly your idiocracy, and stupidity.
The Earth's composition is more relevant to the the Nebular Hypothesis for the formation of solar systems is more appropriate to explain the origin of planets. However, the Big Bang creation event did provide for the matter and energy which eventually facilitated the formation of black holes, galaxies, solar systems and then the planets.
A comet has no atmosphere.
There is no atmosphere for the solar system, space has no air
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
Yes, earth's atmosphere is unique among the planet in our solar system. Our atmosphere is largely nitrogen and oxygen. It varies in composition on \Venus and the gas giants, but at first glance, the most typical atmospheric gas in our solar system would seem to be methane. Earth is very different in that regard.
Its composition is usually rocky or metallic.
It is similar to the composition of the atmosphere of Venus. They are both made almost entirely of carbon dioxide.
