Most of the comments so far are about the temperature and the closeness to the sun, and, hey, I get it: those are both amazing to think about. But to me even more amazing is... 0.16% of the speed of light?? Yikes.

It weighs half a ton. Getting it to even 10% of the speed of light would take more energy than is produced by the world in a year.

It wouldn't be in orbit of the sun anymore
