I have a fish solar system of my own, but they're eight common, comet, and shubunkin goldfish residing in my pond. Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Saturn and Mars are replacements already, as the original two died when my pond overflowed due to a very strong rain and a cat got to them. :(
I usually don't name fish but planets are good names for them, don't you agree?
