Every known spacecraft began on earth and went to other places. That's also
true of every known drawing, component, fragment, subsystem, and model of
spacecraft. Few of them ever returned to earth.
All of the eight planets have been visited or orbited by space probes.
The Mariner Ten and the Messenger
It's not clear what you mean by "visited", here. All man-made spacecraft ORIGINATED from Earth. Some of them later RETURNED to Earth as well, and quite a few of them were designed to STUDY Earth (for example, weather satellites).
No spacecraft has visited all the planets.
Nobody knows for sure. If they do know, they aren't telling.
It's the closet and rather similar to the earth.
Pluto will be visited by the spacecraft New Horizon in 2015
Yes it was named Magllan and in 4 years
A spacecraft left earth in late 1957 and returned in early 1958. Other than human spacecraft, no alien space craft has ever left or come to visit our planet, that we know of. It is possible some alien space craft may have visited earth millions of years ago. It is highly unlikely any craft has done so within the past few centuries.
Some notable satellites and robots that have visited Earth include the Hubble Space Telescope in 1990, the Juno spacecraft in 2011, and the Parker Solar Probe in 2018. These missions have provided valuable data and insights into Earth and our solar system.
Yes. Every spacecraft ever made by humans originated on Earth and most never went farther than an orbit around Earth. Many have returned to the surface.
