How many satellites in sky?
There are thousands of satellites currently orbiting the Earth. The exact number can vary, as new satellites are launched and old ones are decommissioned regularly.
Why are old satellites brought back from space?
Unless they are especially valuable or designed to be returned, they aren't "brought back". They simply fall back as their orbit slows relative to the earth due to drag from gravity, magnetic fields, dust and gas. To keep a satellite in orbit permanently it would have to be moved up periodically (some can do this on their own). Sometimes satellites run out of the fuel they need to have their orbits adjusted to keep them in the right place. Geostationary satellites need to be moved every two weeks.

What is the difference between weather satellites from communications satellites?
Wheather satellites are used to take close pictures of the earth . Communication satellites are used for communication. Ex(in the old days if you sent a letter from Canada to Russia it would take 25 days. Now you write in MSN, it goes to the satellite and to the reciever.)
When a planet or one of its satellites casts its shadow on another planet or satellite what happens?
you can see a shadow on the planet and its so cool
