If it is close to Earth, it would need a speed of 11.2 kilometers per second to escape from Earth.
escape velocity of satellite is greater
a probe need to travel escape velocity while a satellite travel orbital velocity.
Charon is the largest satellite of the dwarf planet Pluto and has an escape velocity of 0.36 mi/second or 1,296 miles per hour.
Escape velocity
surely a rocket or artificial satellite can get out with help of escape velocity....
Well, a satellite revolves about 80 times faster than the probe. The probe masters different situations which cause orbital problems. Escape velocity doesn't have the power that regards to the probe. Scientists assume that the satellite has the power, but others don't. The probe connects to orbital velocity and has the power to control it.
Escape velocity is the velocity that an object needs in order to reach infinite distance, wherein the force will equal to zero. Orbital velocity is the velocity of an object so it can stay in orbit.
If a satellite somehow acquires too much velocity for the orbit it's in, it moves to an orbit for which that velocity is just right. That's how artificial satellites are placed into the desired orbit ... engines are fired to give them the velocity that's correct for the desired orbit, and that's where they go.
Its mass won't affect the orbital velocity.
Each asteroid has its own escape velocity.
Escape Velocity Nova happened in 2002.
Escape Velocity Override happened in 1998.
