why was pluto taken out of the solar system?

Answer 1

Because a whole lot of very very intelligent men were paid a fortune to sit around and discuss the mind blowing problem of whether or not it was a planet. They had to work out what the characteristics of what a planet would be and it didn't quite qualify.
How much better their great minds would have been put to use discussing real issues like, how to end poverty, how to stop war and so on, but then again I suppose it takes all sorts.

Answer 2

As far as I know, they have put Pluto back into the Solar System, along with 2 other planets they call Plutonian planets. I've checked it out and I think like most things some scientists will keep accepting it as the 9th Planet, despite the size, while others will argue that it is too small to be called a planet, but on the whole, all the latest Solar System Charts have Pluto included.

Answer 3

It has long been clear that Pluto, discovered in 1930, stood apart from the previously discovered planets. Not only was it much smaller than them, only about 1,600 miles in diameter, smaller than the Moon, but its elongated orbit is tilted with respect to the other planets and it goes inside the orbit of Neptune part of its 248-year journey around the Sun.

Pluto makes a better match with the other ice balls that have since been discovered in the dark realms beyond Neptune, they have argued. In 2000, when the new Rose Center for Earth and Space opened at the American Museum of Natural History, Pluto was denoted in a display as a Kuiper Belt Object and not a planet.

According to the new rules a planet meet three criteria: it must orbit the Sun, it must be big enough for gravity to squash it into a round ball, and it must have cleared other things out of the way in its orbital neighborhood. The latter measure knocks out Pluto and Xena, which orbit among the icy wrecks of the Kuiper Belt, and Ceres, which is in the asteroid belt.

Answer 4

Well... Pluto is still in our solar system. It is just now classified as a dwarf planet instead of a planet.

Answer 5

They have now decided it is too small to be a proper planet and have called it a micro planet or somehting.
I think it's down to them having more advanced telescopes and over the years they have found other planets that are larger than Pluto - i might be wrong about the last bit.

Answer 6

1. Pluto was the smallest
2. Pluto aa d Neptoon crossed
3. Pluto was more tilted then any other plant

Answer 7

well i think it is still yet under debate and open to review, so its still a planet yet. but its always been the odd one out. its wierd orbit, tiny size and just happens to look the same as other kuiper belt objects, its just it happened to be the biggest, well until they found Xena (its unofficial name by the way). so its though there could be lots more kuiper belt objects bigger too. this means adding planets all the time, i think its easier to remove pluto, well until they find one bigger than mercury lol

Answer 8

They have finally find out it's a small and far planet to be considered one of our solar system !!

Answer 9

because they sed Pluto f off
nah probably cuz its o cold it got turned into a rock but it has everything a planet has like a moon, a core an atmosphere so it should still be a planet but it is -275degrees

Answer 10

Astronomers are now calling it a "dwarf planet." Some believe it is really just a large asteroid in the belt of asteroids beyond the planet Neptune.
