Why their is no air in space?

The atmosphere we breath is held round the earth's surface due to earth's gravity. Without this gravity, earth's atmosphere would disperse into space. Because our moon's gravity is weak, so there is no atmosphere on the moon.


What are small fragments that have entered to earth atmosphere and fallen to surface?

If the fragments had their origin in outer space, the fragments to be found on Earth would be called "meteorites".


Which surface would be easier to see Venus or Mars?

From Earth, Mars. We can see the surface with telescopes, because there are no clouds to obstruct our view. However, Venus is a desolate wasteland where the green house effect went wild, and now there are sulfur clouds and rain, and we cannot see the surface.
