My friend Matthew is Gerard Kuiper's grandson. It was fun to see him
sitting in the front row with his family on the Nova special observing the
New Horizons check in.

This whole “planet” or “dwarf planet” is uninspired, in my opinion. They
should be concentrating on “gas planet” vs. “rocky planet.” Then at least
there would be a distinction worth considering when research discloses a
planet’s properties. You can compare gas-to-gas and rocky-to-rocky, but
what’s the point of distinguishing one planet’s ability to “clear out”
their area, especially in light of the near impossibility of that as
presented by Pete’s post?
Also, I’ve been wondering about Pluto’s orbit being at an angle to the
rest of our solar system’s planets. Could this be an indication that Pluto
was captured by our Sun’s (or our solar system’s) gravity after all the
other planets formed out of an accretion disk?
By the way, I have the “Chasing Pluto” and “To Catch a Comet” TV programs
on DVD in case anyone missed it.

Actually size doesn’t come into the equation at all. If Mercury or Mars
were in the Kuiper Belt, they probably wouldn’t clear out their area and
thus not be considered a planet. Pluto’s problem is that it sits at a mean
distance of 39AU from the sun. Along with Pluto, there are some 140+ other
objects at that distance. In fact 39AU has the second most objects that
have been discovered (see graph). As a group, these 140 or so objects are
called ‘Plutinos’. The largest group, at 43AU, are called ‘Cold Classical’
Dwarf Planets.

Also it really gets me each time they say on the news that it is a "former
planet". What, did it get a divorce from the solar system?

Pluto is round like a planet, circles the sun, like a planet, has its own
moons like a planet, and is larger than any Kuiper belt object. It should
be a planet, not a Kuiper belt object. The IAU says pluto needed to clear
all objects out of its orbit, by absorbing or repelling the objects.
However, the earth, mars, and jupiter have asteroids in there orbits that
haven't been cleared. Pluto should be a planet. Take care, Sam

Wow, this is awesome. Does this mean Pluto could actually still be a
planet? Bring Back Pluto!!!

Terri, Pluto is a little larger than previously thought, and is bigger
than any kuiper belt object. It has more moons than thought, it has a
yellowish orangeish color. No geysers have been detected. A lot more data
will be released over the next 24 hours. This is from the NASA TV channel.

Channel 352 on direct TV is the NASA channel and it is showing a lot of
info on the New Horizon mission. Photos, spectrographic info, ultra violet
info, a new measurement of the size of Pluto, etc... Good viewing! Sam

I have the Pluto Safari app on my iPad and one of the options is to
register a personal opinion as to whether Pluto is, or is not a planet.
Many of you know how I feel. I just got an email from them that included
the following paragraph:
"After nearly 7,000 votes, the majority of you - 69% - voted "Yes" to
Pluto is a planet. As new images of Pluto are released by NASA's New
Horizons spacecraft, we have noticed that more 'Yes' votes are being cast,
with some even coming back to change their original 'No' votes.”
Nuf said,
