that is through new definition of a planet, which wrkey published. previously, there has fairly no longer been a scientific definition of what's a planet. The worldwide Astronomers Union (IAU) became into compelled to do something through discovery of an merchandise extra desirable than Pluto (2003 UB313, popularly universal as Xena). would they call this a planet or no longer? The committee they set as much as learn this reported that they define a planet as: a million) great sufficient that its gravity varieties it right into a sphere, and a pair of) independently orbiting the sunlight. This definition would have made Xena a planet, and would have promoted the asteroid Ceres, Pluto's moon Charon, and doubtless dozens of different gadgets to planet prestige. some contributors of the IAU weren't happy with this and further the third requirement, that a planet clean its orbit of different gadgets (that is allowed as much as a million% of its mass in asteroids and different debris). through fact Pluto shares orbital area with Neptune, this new requirement disallowed Pluto, leaving us with 8 planets. the determination has been debatable, with the two the regularly occurring public and with some astronomers, who think of the orbit clearing requirement is unfair and ambiguous. So that is stable for now, yet would ultimately be overturned. yet there probable will no longer be to any extent further variations until the subsequent IAU regularly occurring assembly in 2009.

Depends on your definition of a planet based on size and elliptical orbit. Now it's no longer a planet though, it makes a bit of a mess of all those astrologer's predictions doesn't it? I mean how can Pluto influence you if it's not actually a planet but a piece of ice on an erratic course. Also what about the other 'Minor planet' they've discovered? What about IT'S influence?

Never heard that. I remember in junior high years ago hearing that Pluto might actually be one of Neptune's moons, but I've always thought it was a planet.

Yeah. I hear one day that there are more things considered planets, including a small asteroid, and then I hear that Pluto is no loner a planet. It seems kind of contradictory doesn't it?

well they had to do it. they just discovered all these new things that they weren't sure if they were going to call them planets. and if they did, we'd have like 13 planets or something. it is really weird though, considering how hard elementary school teachers worked to have us memorize them all!
