Personally I would rather they called Pluto a "minor" planet than a dwarf one. I think that would assuage public opinion a bit.

It's easier to offend Dwarfs, than Minorities.

Well, now that they have found that Pluto is somewhat larger than previously estimated I feel they should rethink and amend their original decision about how to classify it. What if they find an object bigger than Mercury in the Kupier belt in the future, how will it be classified?

But it isn't more massive and mass is the criteria.

Colbert to Neil deGrasse Tyson: Pluto 'has a heart, unlike you'
Watch Stephen Colbert try to coax some love for Pluto out of Neil deGrasse Tyson while they eat Klondike bars and discuss drafting in Nascar.


Should Pluto return to the planet club?
In 2006, Pluto had its planet status revoked. Now a petition hopes to get it restored -- but would other dwarf planets ride in on its coattails?

I just read a bit of trivia. The original PlayStation CPU is what is powering the New Horizon space craft as it flew by Pluto.

It is a MIPS R3000 which I used in three workstations while at Trieste Area Science Park in the Nineties. They were UNIX workstations. The main host was a MIPS R6000, a minicomputer with a RISC CPU based on ECL transistors, not a microprocessor, also running UNIX System 5, Happy days!

More images of Pluto.

Welcome to Iceworld: Stunning first hi-def image of Pluto reveals huge 11,000 foot mountains made of water ice and a geologically active surface

The first ever high-resolution image of Pluto has been beamed back to Earth revealing 11,000ft (3,350 metre) mountains made of water ice.

The remarkable image, released alongside new pictures of Pluto's moons Charon and Hydra, provides evidence that geological activity is still taking place on the icy world.

Scientists were shocked to see mountains as high as those in the Rockies that likely formed 100 million years ago - mere youngsters relative to the 4.56-billion-year age of the solar system. Nasa says they may still be in the process of building.

Few, if any, impact craters on either Pluto or Charon. The surfaces of both were presumably 'reworked' about 100 million years ago, or so, allowing little cratering to accumulate since.
The pairing of Pluto with a moon half its size is thought to be the result of a 'giant impact'. It appears that this event may have occurred very much later than the giant impact that is believed to have given rise to the Earth-Moon system.

The obvious geological ferment on both Pluto and Charon could have had its source in the supposed giant impact, other explanations appearing inadequate.

What about the tidal effect that Pluto and Charon have on each other? That should generate some internal heat.

And doesn't the lack of impact craters indicate that Pluto has cleared it's orbital path?

I was thinking about the tidal forces Charon has on Pluto also. I was not certain it was strong enough to cause tectonic motion, but those are certainly mountains. I think the the Kyper Belt orbits as a whole, but I could be wrong about that.

What do you mean by "orbits as a whole"? Everything is in orbit, its own orbit, there isn't a physical connection to cause them to rotate with the same period. They cross each others orbits and from time to time have collisions.

Here on earth we know that tectonic motions create mountain ranges.
But the mountains on Pluto seems to be distributed randomly.
So it's very strange. But that's science:)

who tells u that Pluto is molten inside? without it, very little tectonic is possible...especially in that COLD environment, where everithing is so HARD 6 BRITTLE... ;)
