Scientists have found that the atmosphere consists of several layers. The layers differ in such physical properties as pressure and the types of gasses. The layer of the atmosphere closest to Earth is called the TROPOSPHERE. It contains about 90% of the total mass of the atmosphere. The layer above the troposphere is called the STRATOSPHERE. The OZONE LAYER is the part of the stratosphere where absorption of ultraviolet rays occurs. The layer above the stratosphere is called the MESOSPHERE. The THERMOSPHERE lies above the mesosphere. The ionized gases form a layer within the thermosphere called the IONOSPHERE. The outermost part of Earth's atmosphere extends from about 480 km out to 960 km. This part is called the EXOSPHERE.
Earth's atmosphere has 7 layers. The lowest layer is called troposphere. Rain, snow and wind only take place in the troposphere. There is an upper atmosphere. There is a lower atmosphere. A rocket travels through the 7 layers of the atmosphere. Then the rocket goes into space.
If we count the number of layers cited in this source, we see that the atmosphere consists of seven layers :-
1. Troposphere
2. Stratosphere
3. Ozonosphere
4. Mesosphere
5. Thermosphere
6. Ionosphere
7. Exosphere

A planet may or may not have it's own atmosphere. An anmosphere does not excist in space / vacuum.
The atmosphere of the Earth may be divided into several distinct layers: The Troposphere, The Stratosphere and Ozone Layer, The Mesosphere and Ionosphere

Space is not a complete vacuum, but the particles present are so rarefied that the pressure would be in the range of 10^-12 or even fewer atmospheres.

EXTREMELY close to zero, but not quite. Absolute 0 pressure is similar and related to absolute 0 temperature. Even in outer space, there are a few molecules or particles to create some temperature and pressure.
I've seen calcultions for pressure in space from 10^-11 to 10^-20 Pa.
Here's a reference from a pretty standard text...
Halliday, David. Fundementals of Physics 6th Edition, New York: Wiley. 2001.
Density of Interstellar Space =10^-20 Pa.

Atmospheres is a measure of pressure. Since space is a vacuum, there is no pressure. So the answer is zero atmospheres.

None. Atmospheres is a measurement of air pressure, and since there is no air in space, there is no air pressure.

There are no atmospheres in a vacuum.

atmosphere is the name of the gaz outer-layer of planets and satelites.
What the hell does your question mean?

I think i 'knows' - let's see...it goes troposphere, then stratosphere, mesosphere, thermosphere, exosphere, then NOTHING... (except trace amounts of hydrogen and helium)... try google.
