Planets and Dwarf Planets

It looks like we've got an official definition of planet now, and it excludes Pluto. Yay! Actually, Pluto is now a “dwarf planet”, along with probably a dozen or so other objects in the solar system (including Ceres, previously called an asteroid, 2003 UB213, and others). For some reason they decided not to call Charon (largest moon of Pluto) a dwarf planet. They were going to call these things “plutons” instead of “dwarf planets”, but a bunch of geologists yelled about the fact that “pluton” already has a definition. Like English doesn't have words with multiple definitions already? Oh well.

So, I'm somewhat happy now. Pluto's not a planet anymore, which is what I wanted. It's too bad Luna can't become one, but oh well. I can live with that. 🙂

Das ist alles für heute!
