No space probes have visited earth as all space probes have originated on earth and therefore cannot 'visit' because earth is it's home.
NASA gets it's space probes back to earth by computer commands. However. most space probes are not designed for re-entry and remain in space to continuously monitor planets and such.
My answer is that space probes go 5,075 mph, when launched from Earth. Hope I helped you find your answer.
As of now, there are no manned space probes in space. All probes sent beyond Earth's orbit are unmanned and controlled remotely from Earth. Manned missions have been limited to spacecraft that carry astronauts, such as the International Space Station or missions to the Moon.
We use space probes, and send astronauts... etc.
No, space probes are unmanned spacecraft designed to explore space without carrying humans. They are controlled remotely from Earth by scientists and engineers.
All of the eight planets have been visited or orbited by space probes.
Vega 1 and Vega 2 were the last successful Russian space missions beyond Earth's orbit. These two space probes visited Venus and Halley's Comet in the mid-1980s.

April 2008 At present the only planet in our solar system that has not been visited (either by an orbiting spacecraft or flyby spacecraft) has been the recently planet downgraded body of Pluto. There is a mission currently in motion to visit this distant outpost.
Space probes leave Earth, they do not go toit.
Humans have visited NO planet outside of Earth. Humans have visited the Moon, which is not normally considered a planet.Unmanned probes sent by humans, on the other hand, have already visited several planets.
All but Pluto, which is currently being visited.
Statellites and space probes are orbits that go around the Earth. This is to get data.
The Viking space probes visited the planet Mars
aside from earth, the planet that has been visisted by the most probes, is often said to be mars, however other scientific research has also proven that venus and Jupiter had also been visisted by several probes every 200 - 400 years. mars however is often visited by probes every 50 - 100 years.
