If not, what gases is it comprised. If it is, 'nature abhors a vacuum' so why does it not draw away our atmosphere? Gravity may hold most of it, but on the outer edge of the atmosphere - why not?

Interstellar space is not a perfect vacuum, just "near perfect".
There are still a few atoms and molecules here and there in every cubic meter of space. Most of these are single hydrogen and helium atoms.
The Earth does not lose its atmosphere because the gravity is sufficiently strong to mostly counteract the tendency of gasses to diffuse into a vacuum. We do lose a little over time, but then it is also slowly replenished by volcanoes releasing gasses from under the crust.

People are over complicating things
Yes space is a vacuum
The 'nature abhors a vacuum' quote came from observations done on Earth when surrounded by reasonably high pressure gas - the atmosphere. If you create a vacuum on the surface of the Earth the pressure of the atmosphere will tend to crush the container or leak in somehow. This is not an issue in space.
And yes before people complain I know that space is not a perfect vacuum but it is close enough to not make any difference for any practical purpose.

There is some misinformation in these answers. A vacuum is not the same thing as a suction. Space is close to a vacuum in the sense that there is a lack of pressure, but some molecules exist in every square metre of space. Some atoms in our upper atmosphere do reach escape velocity, due to energy imparted by cosmic rays, and they indeed leave our gravitational pull.

The gravity is what pulls everything out of space. The gravity is what is making space a vacuum. Space will allow light to pass through and not attenuate the light. Even if it has traveled a few million light years it is still clear. All space is evacuated the same way.

They are all wrong with no truth to it at all...so here is what you need to know, space is not a complete vacuum it still has atoms and molecules of hydrogen and helium. As far as the atmosphere goes the molecules don't have enough kinetic energy to escape the gravitational pull of the earth, technically speaking molecules need to have about six times the escape velocity of the earth to escape the earth completely.

yes it is a vacume because nothing is in that space
it is not comprised of gasses its just nothingness as for it sucking away our atmosphere it is gravity that holds it down and air and other gasses do have weight so that helps it stay down also

Deep space ain't a complete vacuum.

Antimatter is in each and every way the different of prevalent remember and if the two got here into touch it may react violently like crossing wires from a outlet If it replaced into achieveable to create antimatter in large quantities all we could attain doing could be blowing ours selves into no longer something yet no longer something

according to scientists yes space as a whole is a vacume. but I dont trust them unless they have proof. Any way good question.
