There are three Pluotopalooza Parties brewing locally that I know about, one is right here in West Seattle tonight at the library, another celebration by Astronomy On Tap, tomorrow, July 15th and yet another big celebration at the Museum of Flight on Sunday the 19th. Woo-Hoo, go get yer astrofix!
Oh, what fun! This week the New Horizons NASA Mission to flyby Pluto is coming to fruition. As I have said before, NASA is, by far, my favorite government agency. I am in continuous awe of what the NASA engineers can get done across the unbelievable expanse of space. And they often do it flawlessly. One of the things I learned this week, is how big that Charon, the moon of Pluto, compared to the planetoid. Check out this recent, false-color image of Pluto next to Charon (Note: The distance between the two is also false.) Another striking fact, is that both Pluto and Charon are much smaller than Earth. Below is a depiction that I find striking. Note that this might be fractionally off, because now that we're in the neighborhood, it seems that Pluto is a little larger than we thought. It's still only about the size of the US. One interesting speculation that I have, is I wonder if the flyby mission wasn't launched a few months before pluto was "demoted" from planet to planetoid, if this mission would have taken a different trajectory. No matter, Pluto is still the coolest dwarf planet I know.

These are amazing facts, which I could not even imagine before. Your discovery is unique. I had no idea that Pluto may be a completely different size than we thought.
