There are officially 8 planets and 3 dwarf planets. Yes there were 9, but better detection techniques required a change in classification rules. In the new rules a planet must orbit a star, have enough gravity to be round, and has to have cleared the neighborhood of it's orbit. Pluto has fails the third requirement and was demoted.
The 3 dwarf planets are Ceres, Pluto, and Eris (sometimes called Xena).

Technically till the last few months it was 11 i.e Mercury, Venus, Earth, Mars ,Jupiter, Saturn, Uranus, Neptune, Pluto,Xena & Sedna However with Pluto and planets its size or smaller being decommissioned now the number reduces to 8 with pluto, xena & sedna losing their status and being demoted to the status of being dwarf planets do not qualify to be called planets officially.

It's eleven, in march 2006 the twelvth planet was found but five months later Pluto lost it's status as a planet.
First eight are the known planets to us. three other are discovered within these 2-3 years. I dont know their names. But one is between the Sun and Jupiter, the other between Venus and the earth and the other between Uranus and Pluto.

Officially, 8: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Pluto is now a "dwarf planet" along with a few others.
