Uh... Pluto isn't a planet anymore.



Hey internet quiz!! I totally got all of them in the time! Don't be all 'aww, nope, you missed out Pluto numbnuts!' I was being smart and NOT putting pluto because pluto isn't a planet anymore!! GOSH!

I hate that I can say: When I was a kid, Pluto was a planet.

Sadly, some people adapt to change so slowly.

There is no need to adapt to change when that change is a step in the wrong direction. Pluto is still a planet, in spite of a vote by four percent of the International Astronomical Union, most of whom are not planetary scientists. Their decision was immediately rejected by a petition of 300 professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA's New Horizons mission to Pluto. Stern and like-minded astronomers favor a broader planet definition that encompasses a wide variety of round objects orbiting the sun and differentiates between different types of them through using subcategories. According to this far better definition, a planet is any non-self-luminous spheroidal object orbiting a star. This is because objects large enough to become round have attained a state of hydrostatic equilibrium, meaning they have enough self gravity to pull themselves into a round shape. When this happens, geological differentiation and processes that occur on Earth and other planets begin to occur. These processes do not occur on shapeless, inert asteroids. Using this alternate definition, our solar system has 13 planets, eight classical planets and five dwarf planets (dwarf simply meaning small). The planets are Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Haumea, Makemake, and Eris. This is very much still an ongoing debate, so no one needs to say "when I was a kid, Pluto was a planet" since to many planetary scientists, it still is. There just are more of them now, not less.

Pluto didn't change...what we know and which hairs we split has changed. Nor do we know the date of that quiz -- it might have been "right" at the time it was written.

It's only been two years since Pluto lost its designation as a planet. The current definition is so convoluted and disputed I'd expect it to change again in 2009.

Pluto was Mickey's rabid death-hound which he used to get filthy revenge on those evil incredibly fat twins whose names I can't remember.

but never a planet.

so, no more magic mushrooms for me.

Fascinating comment by Laurel Kornfeld - especially the explanation on how an object reaches a critical size and its own gravity makes it round.

Like the new look for Paperlilies - such a sweet colour scheme. The flop sounds are fun.

Pluto is a dwarf planet & has 3 moons named Charon, Nix & Hydra. :P
