The number of planets in our solar system has been a debatable subject for years. This is because, there is no clear-cut definition of what is a planet and what isn't. Some scientists say that pluto is a planet but others disagree with this. Unless we have a clear definition of what can be considered as a planet, this will be an unanswered questions

I know there are at least 209 observed in the Milky Way Galaxy alone as of 1/26/07. There are 8 in our solar system.
UPDATE: I also read last year (2006) that there were 16 planets identified in a star cluster in an area of the sky about 1/4 of the size of a full moon. One of the planets was a short-duration planet that rapidly revolved around it's star. I'm not able to find a source at the moment.

They think Pluto may not be a Planet,
and there is another Planet beyond Pluto.
So 9 it is.

tough to say. sure, pluto is a 'dwarf planet', but i saw Bill Nye give a lecture a few months ago, and he made this comparison:
is a dwarf human not a human? no! they're just smaller humans! so pluto, the dwarf planet, should still be considered a planet, just a smaller one

According to the IAU's current definitions there are eight planets in the Solar System. In increasing distance from the Sun, they are:
() Mercury, with no confirmed natural satellites
() Venus, with no confirmed natural satellites
() Earth, with one confirmed natural satellite
() Mars, with two confirmed natural satellites
() Jupiter, with sixty-three confirmed natural satellites
() Saturn, with fifty-six confirmed natural satellites
() Uranus, with twenty-seven confirmed natural satellites
() Neptune, with thirteen confirmed natural satellites
Now there are Pluto · Eris but these are dwarf planets I think they should count but scientists disagree.
So I say there are 10...but scientist are not counting Pluto and Eris anymore
But to answer you there are 8
