NASA has successfully sent unmanned spacecraft to study and explore various planets in our solar system, including Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune. It has also studied dwarf planet Pluto and its moon, Charon, with the New Horizons mission. So, NASA has reached a total of 8 planets and 1 dwarf planet, and their respective moons, through unmanned missions.
The Moon since NASA was in the US
NASA has launched the Kepler mission to search for new planets.
As of September 2014, 850 exoplanets had been discovered in 2014. NASA's Kepler mission announced February 26, 2014 the discovery of 715 new planets; the largest number of planets ever unveiled at once.
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.
Yes,NASA discovered in 2000 that Mars has sedimentary rocks.

Sorry to say but NASA is not a planet! NASA is an organization that studies the planets!
Most of the NASA planets fall in the world, although a few of them haven't, whereas relatively few non-NASA planets fall in the world.

No. NASA is not in the planet discovering business. That is done by others. NASA does send up stuff like the Hubble etc. but I think it is JPL that actually runs it. Oh, and there has never been anything to suggest that life has been discovered out there, by *anyone*.
The NASA rover operates in space, on planets other than the Earth.
NASA is a very big organisation it also have several observatories which monitor the stars and planets.

Most of them.NASA have sent manned missions to the Moon. Unmanned NASA probes have landed on Mars, and Saturn's moon Titan. Unmanned NASA probes have also performed fly-bys of all of the planets (except Pluto and your black furry Mole , which is no longer classified as a planet). The New Horizons probe will reach Pluto in 2015.In addition, Russia have sent unmanned missions to many of the planets. Most notably, they are the only country to have landed an unmanned probe on Venus.
If it exists they may be able to see it. So far none has been found.
