Is Pluto a planet?

Answer 1

Not according to the International astronomical union. Pluto is a "dwarf planet:" big enough to be round, but not big enough to count.

There are three dwarf planets, if I recall:
Ceres, Pluto, and Eris. Eris and Pluto both have moons (pluto has three, in fact). And ceres is a big freakin' rock between Mars and Jupiter.

Answer 2

Pluto, discovered in 1930 is not a Planet. It is the second largest member of the icy worlds that make up the Kuiper belt. Pluto has three small moons, Charon, Nix and Hydra. The last two discovered in 2005. It was called the incredible shrinking Planet because of it's downsizing over the years. 1971 est was Earth size, then in 1976 it was said to be the size of Mars. It is now estimated to be much smaller than our moon. The diameter of Pluto is now put at 2300 kilometres with a mass of 0.66 that of Earth.

Answer 3

Is this guy playing with a full deck? "I'm embarassed for astornomy," said Alan Stern, leader of NASA's New Horizon's mission to Pluto and a scientist at the Southwest Research Institute. "Less than 5 percent of the world's astronomers voted."...

I'm embarassed at the 5 percent that voted. What a monumental waste of time for a bunch of supposed adults ("oh yes it is a planet", "is notttttt", "oh yes it is and I said it first") and I am sure it is tax payers money that paid for the time these halfwits used in discussing and voting on it. I guess when you are a mediocre scientist who would be doing more important work by selling nachos at 7-11 then voting on pluto being a planet or not is probably a high point in your scientific career.

Answer 4

Capping years of intense debate, astronomers resolved today to demote Pluto in a wholesale redefinition of planethood that is being billed as a victory of scientific reasoning over historic and cultural influences. But already the decision is being hotly debated.

Officially, Pluto is no longer a planet.

"Pluto is dead," said Caltech researcher Mike Brown, who spoke with reporters via a teleconference while monitoring the vote. The decision also means a Pluto-sized object that Brown discovered will not be called a planet.

"Pluto is not a planet," Brown said. "There are finally, officially, eight planets in the solar system."

The vote involved just 424 astronomers who remained for the last day of a meeting of the International Astronomical Union (IAU) in Prague.

"I'm embarassed for astornomy," said Alan Stern, leader of NASA's New Horizon's mission to Pluto and a scientist at the Southwest Research Institute. "Less than 5 percent of the world's astronomers voted."...

Answer 5

We menbers of the Pluto Liberation Unification Group (PLUG) Believe that Pluto has been greviously wronged by this Planetist thinking. What makes planets any better than asteroids or chunks of frozen rock? Pluto has rights and feelings just like any orbiting object. If Pluto wants to think of itself as a planet, who are we to judge otherwise?
