No space probes have visited earth as all space probes have originated on earth and therefore cannot 'visit' because earth is it's home.
Curiosity opportunity and spirit
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.
The space shuttle is an Earth orbit vehicle. No humans have ever travelled to any body other than the Moon (from 1969 to 1972). All other space exploration has been by unmanned probes.
We use space probes, and send astronauts... etc.
All of the eight planets have been visited or orbited by space probes.
space probes have crossed Pluto's orbit, but never have visited the planet because Pluto was not in alignment with the flight path of the 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.
yes lots of space probes
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.
Statellites and space probes are orbits that go around the Earth. This is to get data.
All but Pluto, which is currently being visited.
The Viking space probes visited the planet Mars
