More precisely, close to the speed of light. They are actually in free fall in a deep vacuum and nothing slows them down. It is quite possible to have 200 thousand km per second without a noticeable increase in mass. But their speed is much less. Why?

The gravitational attraction of larger celestial bodies slows them down.

read about the potential. From whatever height the body does not fall to the ground, it will accelerate to a maximum of 3 space (11 km / h), if it starts from 0 speed relative to the earth. The same goes for the rest of the space objects.
