For those of you hoping that dwarf planet Pluto would get its full planethood status restored again, the news isn't looking good. The most recent observations peg the newly discovered dwarf planet Eris as being 27% more massive. ...

Pluto never gets any respect in our solar system anymore. Although its a bit smaller than it's Kuiper belt friend, it probably has higher chances of being settled (or at least mined) than its distant buddies (including Eris).

Aye. Poor Pluto. All those years of waiting for Disney to return it's calls and now this.

Seriously, we've only know of Pluto's existence for less than a century. The outer solar system is only beginning to be mapped so there may be more changes yet.

definition of a planet: If you can morris dance on it, it's a planet.

Thou shalt not mention that name. It was 2003 UB313 before.

Why can't people just describe Pluto for what it is; by far the largest member of the Kuiper belt? That gives it more status than being the smallest, weirdest and least understood planet.

Because it isn't the largest member of the Kuiper Belt!

Only if you consider the scattered disc part of the Kuiper belt, which personally I don't because if we considered the SDOs KBOs we'd have to start calling Halley's Comet a KBO.

You're right, I see that it orbits beyond the Kuiper Belt (http://en.wikipedia.org/wiki/Scattered_disk). I didn't know about the Scattered Disk.

people that grew up in the 80s will always think of Pluto as a planet. I'm one of them.


But Pluto doesn't have a mostly circular orbit or even one in the plane of the Solar System. Anyway, science books are all out dated and have to be changed now. :/

Well I know I'm looking forward to the time when Pluto can come up in conversation without starting yet another huge debate on peoples' personal definitions of "planet" again (because it's not like it hasn't happened a hundred times already)... ;)

That is the worst argument people usually give. Things change, including our knowledge. Get over with it.

People sometimes make comparisons between the planets and continents: It is true both are more or less culturally defined. Europe is similar glaring exception as Pluto was; I suggest that Europe is demoted to a sub-continent of Eurasia. After all, it is a ridiculously artificial construction. :)

Well, there were few if any pre-demotion books about the Solar System that were anywhere close to up-to-date...
