in 2006 the IAU(international astronomical union) passed out this resolution that changed the definition of a planet, it says that a planet must be a celestial body that oribtis around the sun, has a round shape, and has a clear neighborhood around itz orbit. Pluto sometimes crosses over to Neptune therefore it is not a planet, however, wat i dont get is, Venus and Mercury is located in Earth's orbit, y are they still considered to be a planet?

that rule is only appiclicable to exo planets not the inner planets...and for your info .....venus and mecury never crossover....and if they come to earths orbit....their will be massive gravty faced by earth...and we get major earthquakes...the distance fro m earth to venus is 40 million km (25 million miles)...and venus is more far than that...
77.3 million km (48.0 million miles) is the distance from earth and mercury.....i think this convinced you Mar 25

A lot of the controversy revolved around Pluto's size, another part of the argument had to do with Pluto's highly elliptical orbit (it wasn't regular enough to suit some astronomers).
The remaining 8 planets all have 'regular elliptical orbits'; i.e., they don't cross one another's orbital paths.
Personally, on that clear space thing, then Jupiter, Saturn and Uranus should probably be thrown out, because of the irregular inner rings they all have. Jupiter also has the trojan point asteroids, 60 degrees in front of and behind the planet in it's orbit.

actually pluto has an orbital radius of more than 5000 km,hence not considered as planet apart from ur reasons.
in the similar manner the reason u gave is not up to the mark.
EXTRA INFO:
The remaining 8 planets all have 'regular elliptical orbits'; i.e., they don't cross one another's orbital paths.
HONESTLY SPEAKING,Jupiter, Saturn and Uranus should probably be thrown out, because of the irregular inner rings they all have. Jupiter also has the trojan point asteroids, 60 degrees in front of and behind the planet in it's orbit.

Dude, I think Yahoo! Answers is not the best place to look for this answer. I thought Pluto was 'disbarred', so to speak, because of its size and similarity to the ancient asteroids in the belt that flank its rear-most side? Of course, I'm probably wrong.

xcuz me,,,,first u should know thst venus and mercury are not located in the earth's orbit!!!ofcouse they still are planets.
