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.
They study how long to get to planets and if there is life in outer space.
Astronauts have sent robots to explore the following planets: Mars, Venus, and the Moon. These robots, such as rovers and landers, have been used to gather data and conduct experiments to further our understanding of these celestial bodies.
Astronauts can see planets, stars, and species.
They could, but as of now, no astronauts have travelled to any other planets in the solar system.

Well, to explore space ofcourse. Astronauts go to space to find new planets or such. They observe what is happening.

No, not yet at least. The only object that astronauts have been to other than Earth is the moon, which is a moon rather than a planet. There other planets are much farther away, but there are some plans to land people on Mars.
Yes. Astronauts do study the moon. In particular, Astronomers study the planets, stars and outer space.
