Currently (December 2008) 333 exoplanets are confirmed. That figure is expected to skyrocket when Keppler comes on line.

What is Mariner 2?
the first encounter with another planet. it was a spacecraft sent by NASA to venus. it measured venus' temperature and is now thought to be orbiting the sun.
When was the first planet discovered outside of our solar system?
The first confirmed detection was in 1992, with the discovery of several planets orbiting a pulsar. The first confirmed detection of an exoplanet orbiting a main-sequence star was made in 6th October 1995, when a giant planet (51 Pegasi b) was found in a four-day orbit around the nearby G-type star 51 Pegasi.

When Earth was discovered?
Earth was not discovered by anyone. It was here long before the first mammal set foot on the planet. Earth was eventually found to be the third planet orbiting the Sun in the solar system. Although its spherical nature was surmised by the Egyptians, Sumerians, and the Greeks, it was not until the time of Copernicus in the sixteenth century that the Earth was commonly understood to be a planet orbiting the Sun.

Did Galileo find any other planets?
No. He discovered great moons, which, had they not been orbiting planets might have been considered planets themselves, but the first new planet since antiquity was Uranus, discovered by Sir William Herschel.

How many moons does Jupiter have in its orbit?
There are no moons in Jupiter. Jupiter does have 63 confirmed that are in a stable orbit around the planet though. There could well be more than this though, which have yet to be discovered.Jupiter have 64 moons.
