Can't remember the 11 planets? 4th-grader offers help
What? I said. (Out loud. To my purse. I was that appalled.)
Now see, I remember when Pluto was downgraded. My entire childhood, invalidated by some sadistic astronomers. I remember that day, though I don't know when it was, because it was hard. So hard.
The 11 recognized planets are Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto and Eris.
Ceres, Pluto and Eris are considered dwarf planets.
I didn't say what again: I was too horrified.
So like any good netizen, I went to Wikipedia, the bastion of all knowledge. They'll sort this nonsense, I told my laptop. (Out loud. Because I can.)
Under IAU definitions, there are eight planets in the Solar System (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) and 270 extrasolar ones. The Solar System also contains at least three dwarf planets (Ceres, Pluto, and Eris).
It still hurts to see Pluto retconned like that. But this business of putting then all in together? Ceres? Who ever wanted a planet called Ceres?
Okay, Eris is not the moon of Pluto. That would have been insult on top of injury. Thank you, green_grrl. BUT IT IS STILL A DWARF PLANET. GAH.
So hied myself to the AUI--the International Astronomical Union, the people who first wrecked the Nine and made them a lesser eight. The website won't load. I am going to stare at it until it loads.
