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.
There are many planets in our solar system that have not been visited by a spacecraft. As of now, the planet Uranus has not been visited by any spacecraft.
No human has really visited any planet other than Earth; the Moon isn't a planet. However, spacecraft have visited other planets, such as the Spirit and Opportunity rovers, who went to Mars
Astronauts have visited the Moon, which is not a planet but a natural satellite of Earth. Other than the Moon, astronauts have not visited any other planets in our solar system. Only unmanned spacecraft have been sent to explore other planets.
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.
The only planet astronauts have visited is earth. The moon, a satellite, has also been visited.
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.
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).
The first planet to be visited by spacecraft was Venus. The Soviet spacecraft Venera 1 was the first to fly by Venus in 1961, followed by flybys and landings by subsequent missions from various countries.
there isn't any proof of any alien spacecraft even exists but even if aliens exist they would have some sort of spacecraft to go to earth in because there isn't any other known way of getting living things from planet to planet.
No. Astronauts have not visited any planet outside of the earth.The only other body in the universe besides earth that humans have ever stood on is the moon,and that hasn't happened in the last 32 years.
Yes, there are satellites in orbit that record information about our planet.
nasa technically didn't visit any planets yet, but it has visited the moon (and was the first to send people to the moon), and it has also done many missions into lower earth orbit.
