Astro was born from the stardust and gasses from a dying planet and has seemed to remain around the same general age. He has always looked like a kitten and he will, apparently, continue to remain so. He lives within the deeper reaches of the galaxies, but seems to find himself flying through black holes from time to time, entering new atmospheres and finding new galaxies and planets. Not many see him, and he doesn't usually land on planets, but he does like to play within the asteroid belts.
