Well, with the exception of Pluto being downgraded to space debris or an asteroid or whatever, there is 8. However, Astronomers discovered a body outside of Pluto's orbit about two years ago. They started searching for the possibility of a tenth planet when they noticed that Puto's orbit was irregular. At this point, I do not know if this other celestial body has been confirmed as another planet or not. So, if you include Pluto and this unconfirmed body, there is 10.

There are currently 8 planets in the solar system.It was 9 until they discover that Pluto was too small to be a planet.

According to the "geniuses" at the National Science Association, there are 8. But screw that, the planets in our solar system are the only things that got me through the Greek/Rome mythology test a while back.

There are eight planets in our solar system.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Sedna is bigger than Pluto, so if Pluto is a planet, so is Charon (the largest of Pluto's three known moons), so is Sedna, so is Varuna, so is Quoaor, and why not Ceres? Our MOON is bigger than Pluto.
The reason Pluto is NOT a planet is because it has not cleared its orbital path of such debris. It cannot, until it swells up more, which is unlikely to ever happen.
The definition of a planet is not all that great, but it works for me.

You already knew the answer when you posted this question, which begs the follow-up question, Why do you ask?
There are, of course, nine planets in our solar system - there always have been, and there likely always will be, at least in our lifetimes. That a markedly small minority of the assembly voted otherwise does not make the answer 'eight', and those respondents here that answered 'eight' have it wrong (there are few absolutes in life, but this is one of them).
You have to decide who (or is it whom?) you're going to accept as an authority. But like I say, the correct answer is nine.
