And not teaching them that it's TOO small and TOO far, not TO smile.gif

The real argument is one that will doubtless cause many a conference-argument for decades, personally, I think Pluto deserves it's title as it 'got there first' so to speak, and then the similar bodies out at that sort of range with that sort of composition should be refered to as Plutonian's or part of the Pluto 'class' of bodies.

Seems like the term "ice dwarf" is catching on. Though I really like edstrick's "giant cosmic dust bunnies". Think the IAU would go for that? wink.gif

I'd go for Xena! No wait, I don't think that's what you meant....

I agree with Doug about considering them the "Pluto Class" of bodies..... bodies.... um, just got distracted there for a minute... What was that about Gabrielle?

The IAU won't accept *that* term, due to it's Political Incorrectness.

Thet *might* go for 'Thermally-Disadvantaged Planet of Restricted Growth' or TDPG - see, it trips off the tongue, doesn't it!

Exploring the acronym idea and considering the difficulties the IAU and others are having I propose:
ODDS - Outer dim and Distant Systems (For objects with satellites)
SODS - Solar Orbiting Distant Spheres. (For solitary planet like objects)
and perhaps at a stretch
DEMONS - Distant Embarassing Minor Orbiting Natural Spheres

Sorry to dredge up an older topic...however, there was talk of the 'is Pluto a planet' in another forum that I wanted to respond to but it would have been off topic.

According to the wikipedia entry for 'Planet'...The name comes from the Greek term πλανήτης, planētēs, meaning "wanderer", as ancient astronomers noted how certain lights moved across the sky in relation to the other stars.

So therefor only Mercury, Venus, Mars, Jupiter and Saturn are 'Planets'. Since 'Planet' already has such a definition, let's move on. We need a word or words for rocky worlds and gaseous worlds. There should be a lower size limit to exclude debris. Our asteroid belt, and now TNOs/KBOs, make this more difficult as there's such a range within a given volume of space.

I'm sure whatever the IAU does decide it will be unpopular with one group or another.

I'm in favor of the word "Orbiter", as in "The orbiter Earth", "Third orbiter from the sun".

Planet - classical planet
Planetoid - planet-like
Asteroid - star-like
Comet - classical comet
