Whether you think Pluto is a planet, a dwarf planet, a Kuiper Belt Object – or something else entirely – you should still be fascinated by this: a video of the dwarf planet Pluto and its largest moon Charon showing the two distinctly separate worlds actually in motion around each other! Captured by the New Horizons spacecraft from July 19–24, the 12 images that comprise this animation were acquired with the Long Range Reconnaissance Imager (LORRI) instrument from distances of 267 million to 262 million miles (429 million to 422 million km) and show nearly a full orbital rotation. Amazing!
Is Pluto a planet? A dwarf planet? A Kuiper Belt Object? All — or none — of the above?
Pluto has been a topic of scientific fascination since Clyde Tombaugh discovered it in February 1930, and then a topic of controversy after the IAU reclassified it as a dwarf planet in 2006. While conversations continue over Pluto’s planetary identity, at least one theme carried through the talks at the Pluto Science Conference in July 2013. See if you can figure out what it is in the video above! (Hint: it’s not difficult.)
NASA’s New Horizons mission will help us understand worlds at the planetary frontier by making the first reconnaissance of Pluto in July 2015. Read more about the mission here.
It’s a journey spanning 85 years and billions of miles: humanity’s first-ever encounter with the dwarf planet system of Pluto and Charon, located in the frozen far reaches of our Solar System where our entire planet is a barely-visible pale blue dot — just a “mote of dust suspended in a sunbeam.” Launched in 2006, the New Horizons spacecraft will pass by Pluto in July 2015 and send back images and data in unprecedented detail, 85 years after its discovery. With the flyby just about a year and a half away, the excitement in the space community is rapidly building even now.
The video above is a “teaser” for the event from the Applied Physics Laboratory at Johns Hopkins University — check it out. (Warning: may contain scenes of intense scientific discovery!) Also, watch a longer documentary below on the history of Pluto and the New Horizons mission:

The two bright clusters of pixels in the image above might not seem like much of a big deal, but they are… those two blocky blobs are the dwarf planet Pluto and its largest moon, Charon, as seen by the rapidly-approaching New Horizons spacecraft, destined for its ultimate close encounter in July 2015!
This represents a major milestone on the spacecraft’s 9½-year journey to conduct humanity’s first close-up reconnaissance of the Pluto system and the Kuiper Belt and, in a sense, begins the mission’s long-range study of the Pluto system.
And that’s a very big deal indeed. Read on, fellow space fans…
I’ve written about this a couple of times before and put up polls here on Lights in the Dark, but now it’s actually semi-official: you can vote on the names for Pluto’s newest moons!
(Looks like they may have taken some of our earlier suggestions too!)
Since we’re all in the democratic mood here today in the U.S., how about another chance to put your vote in on something: names for Pluto’s newest moons!
Real planet, dwarf planet, KBO… who cares? What matters here is that astronomers from NASA, NOAO and the Gemini Observatory have created the sharpest image of Pluto ever made with ground-based observations — and developed a new way to verify potential Earth-like exoplanets at the same time. Not too shabby, I’d say.
