And more Pluto trivia. The sky on Pluto, day or night, would be utterly spectacular because there's no atmosphere and the Sun is so far away it would just be a bright star with no apparent disk. However, even as just a bright star with no apparent disk, if one stared at it without eye protection, it would damage your eyes. Not as quick as on Earth of course, but you still wouldn't want to actually stare at it.
While on the topic of Pluto, before the flyby astronomers expected they would photogragh a geologically dead heavily cratered orb like the Moon. Its core should long ago have cooled and so far from the Sun there should have been no energy source to drive geology. Instead they found an object that clearly has a geologically active surface, and as yet it's still a mystery from what I can find online.
i miss pluto. i don't care if it's a dwarf planet or an ice planet. you can't just give that kind of status to an entity and then rudely take it away. pluto needs to be reinstated, and if that means letting all its icy little friends join too, then so be it!
