Jupiter has been explored multiple times by multiple space probes, each sent for varying purposes. Some were sent to study the surface, some to study the rings, others to study the magnetic field and so on.
- Pioneer 10. December 3rd 1973.
- Pioneer 11. December 2nd 1974.
- Voyager 1. January 4th to April 13th 1979.
- Voyager 2. April 25th to August 5th 1979.

Well, no. It has not been explored by anyone. It is currently the most inhospitable planet in the solar system. We can't land on it successfully.
Jupiter is the next planet after Mars, but there is small minor planets in between that's within the asteroid belt, with best known been ceres, expected to be explored by the Dawn Spacecraft in 2015.
