Comments on: As surely as the Sun will rise in the East… http://blogs.discovermagazine.com/badastronomy/2007/07/06/as-surely-as-the-sun-will-rise-in-the-east/ I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.

And Voyager 2. And Apollo 11. The trouble is, Phil, NASA has launched too much cool stuff... “surely one of the coolest things NASA will have ever launched”

This makes it about 1/3 the volume of Luna. With reduced density Ceres would have a gravity well small enough (about 0.1G perhaps) to manage, but still large enough to allow landing craft to stay in place. If it is truly comprised of a large amount of water, wouldn't that make Ceres an ideal refuling spot for future missions? According to NASA’s Dawn page, Ceres is 975/909 km in diameter.
