Planets

[kinch]

I feel that Sedna and these new ones should be planets if Pluto is, and not if Pluto is demoted. They should definitely all be in the class though - Kuiper belt objects with eccentric orbits outside of the "normal" solar system.

If we do include them as planets (and Pluto) then we may need to include other large objects as planets as well, such as certain asteroids that are very large.

For that matter, why don't we start classifying things with whole new names? Isn't Europa closer to an Earth than other moons? Should Jupiter be a new "sub-system" consisting of a "mega-planet" with orbiting "planetoids?"

What about brown dwarfs and planets? Where should the line be there? Should it be based on size, distance, climate, orbit, satellites?

Whatever. Just kick pluto out and keep our system as it is, answer the questions above before we start figuring out what to call the new systems discovered.

. . . and name our damn moon.

Our moons name is Luna. It has been since the ancient Romans named it that 2,000 or more years ago.

Luna is the latin word meaning moon and in greek mythology Luna is the goddess of the moon. That is where we get the word Lunar as in lunar eclipse.

I believe that is the latin name, but not our name. I don't think we have one other than the Moon (capital m).

Or, if you are right, than I suppose I live on Terra, not Earth.

Or, put another way, Terra is to Earth as Luna is to ??? the Moon. Bleh.

Let's call it Evilon and declare war with it as our mortal enemy planet. It is pretty big, after all.
