How fast can a satellite go?

The circular orbital velocity of a satellite in low earth orbit is about 7 km/s (7.9 to be exact) or 25000 km/hr or 17500 miles/hr. If it reaches sqrt(2) times the circular velocity, it will escape from earth orbit and go into orbit about the sun.

The current record holder for a man made object is the New Horizons probe, which left earth orbit at 16 km/s.

A satellite can travel 5 miles per second, therefore that equals 300 miles a minute. So that means a satellite travels at an unbelievable speed of 18,000mph . THATS VERY FAST!!!!!!!!


To be honest with you I can't believe that there is a person alive that doesn't know how to get to the moon. However, that being said, you have to go by rocket so join the Navy or Air-force and fly away. (That is not the answer he want)
