I'm waiting for some real images of more than just a few pixels before getting my excitement level up to fever pitch. But at least the cameras are working.

NASA’s New Horizons Spacecraft Nears Historic July 14 Encounter with Pluto

NASA’s New Horizons spacecraft is three months from returning to humanity the first-ever close up images and scientific observations of distant Pluto and its system of large and small moons.

"Scientific literature is filled with papers on the characteristics of Pluto and its moons from ground based and Earth orbiting space observations, but we’ve never studied Pluto up close and personal,” said John Grunsfeld, astronaut, and associate administrator of the NASA Science Mission Directorate at the agency’s Headquarters in Washington. “In an unprecedented flyby this July, our knowledge of what the Pluto system is really like will expand exponentially and I have no doubt there will be exciting discoveries."


This latest image (shown) reveals Pluto and Charon.

If one figures that just about every possible combination of sun/brown dwarf/
"planet" formation is possible -- including formation of "planets" without
being in the range of gravity of a sun, plus those which have been ejected
from solar systems, the definition of a "planet" is going to be modified
a bit, as knowledge grows.

I, personally, don't care one way or the other if Pluto is classified as
a planet/dwarf planet/whatever. It would be interesting, if an earth-sized
(or larger) planet should be discovered in the Oort Cloud. Even better,
would be if it could be later discovered that it was captured by our sun's
gravity, from a passing sun's system.

It's a universe of almost infinite variety. Classification, hence, can
become more dicey, the more pieces of that variety become known. A good
example of this is seen with discoveries in the various evolutionary
trees, on Earth.

Pop quiz! Without looking it up because that would be cheating.

What's the difference between a plutoid and a plutino?

A plutoid is a dwarf planet orbiting beyond Neptune. That would include dwarf planets in the Kuiper belt and scattered disk, like Eris. There is some debate about the name, some people call them ice dwarfs.

A plutino is an object with an orbit similar to Pluto's, specifically a 2:3 resonance with Neptune (the body makes 2 orbits around the sun for every 3 orbits Neptune makes). Meaning it is on average about the same distance from the Sun as Pluto. A plutino doesn't have to be a dwarf planet. The biggest known one is Orcus at 750 km diameter.

I thought it was a vote regarding Pluto's status as a planet. I discovered they are voting to name surface features.

Everybody has missed the whole point here!!! Sigh.

SCIENTIFICALLY the Planet formerly known as Pluto has, because of the newest up to date information, been re-designated as a dwarf planet, not as a main one by the IAU.

OK, SCIENTIFICALLY that may well now be a correct designation, and in fact Pluto is the second most massive dwarf planet with Eris being the most massive.

However, the vast majority of the worlds public grew up to be taught, and to understand, that Pluto was the official 9th planet orbiting the Sun. They want to continue to believe that despite Scientific evidence to the contrary. And as far as I can see there is no reason why we shouldn't continue to call Pluto a full planet. The scientists in their closeted little world can call it what they like, (actually 134340 Pluto) it simply has no relevance to everybody else.

So don't get all uptight just ignore them, carry on as usual, they will in their own way, so should you!

New Horizons Sees Pluto and Charon

This series of New Horizons images of Pluto and its largest moon, Charon, was taken at 13 different times spanning 6.5 days, starting on April 12 and ending on April 18, 2015. During that time, the NASA spacecraft's distance from Pluto decreased from about 69 million miles (111 million kilometers) to 64 million miles (104 million kilometers).

The pictures were taken with the New Horizons Long Range Reconnaissance Imager, or LORRI. Pluto and Charon rotate around a center-of-mass (also called the "barycenter") once every 6.4 Earth days, and these LORRI images capture one complete rotation of the system.

First time I see a moon and a planet rotate around a center-of-mass.
The same when our Moon rotate around the Earth:)

Pluto May Have Icy Cap

The latest images from NASA's New Horizons spacecraft show a bright spot near the dwarf planet's pole

Images from NASA’s New Horizons spacecraft suggest that Pluto has a polar cap made of some kind of ice.

The pictures, taken over the past few weeks and released on April 29, show Pluto with its largest moon, Charon. The dwarf planet’s surface is mottled with light and dark patches, each measuring hundreds of kilometres across. But its pole remains bright no matter how Pluto rotates, suggesting that a highly reflective icy cap may exist there. “It’s very suspiciously suggestive,” says Alan Stern, the mission’s principal investigator, who is based at the Southwest Research Institute in Boulder, Colorado.


A bright spot on Pluto (right) could be nitrogen ice. The dwarf planet is shown with its largest moon, Charon.
