yes, pluto is not a planet. there are eight planets in the solar system, mercury, venus, earth, mars, jupiter, saturn, uranus, and neptune.
pluto does orbit the sun, is ball-shaped, does not have an isolated orbit (a bunch of other similar bodies have similar orbits.), and is not a satellite so it is not a planet. this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially. i don't know how long this will drag on tho. many planetary astronomers are not satisfied that the definition is rigorous enuf. i can accept that the definition is flawed, but i can not accept that pluto is a planet.
many astronomers consider pluto and charon to be a binary system, but two small bodies orbit that system. they are called nix and hydra.
i have been waiting for this since i was about twelve. i feel somewhat satisfied. i knew that pluto didn't fit the pattern set by the major bodies in the solar system so it was an anomaly. it just felt "out of place". now that astronomers have found hundreds of other bodies with similar orbits, classifying "134340 pluto" as a planet is even more irrational. this was the right thing to do, believe me.
incidental, "134340 pluto" was never a moon of neptune. neptune did capture triton. this is why triton has a retrograde orbit.also, "13199 eris" is about five percent bigger than "134340 pluto".

we used to have 9 official planets in our solar system. But Pluto has just recently been lowered to a status of minor plantet, along with other objects that are extrasolar, or outside of our solar system. the 8 official planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Those are in order from closest to farthest to the Sun.

Well yes Pluto has been erased.
So now we have (in order). Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus (not pronounced ur anus), Neptune. And the new ones are Sedna, Planet X and UB40 2003.
So there are 11 planets altogether. Hope that helps!!!

Pluto is no longer a Planet. We have 8 total now in this order:
Mercury, Venus, Earth, Jupiter, Saturn, Uranus, and Neptune.

Well, if we had 9 planets, and we took one off the list, that would leave us with 8.

eight planets, there are some other discoveries that have not been regarded as planets yet because of their size or their orbit path around the sun

we've had 9 for the last 70 years or so, but now we have 8 because scientists are annoying.
