I like to use names from Roman and Greek mythology. I'm currently running through the planets, which were all named for gods anyway. I named my latest addition, Jupiter. My next one will be named Saturn if it's a Pinstripe combo or Pluto if it's a Pied combo.
I realize Pluto is no longer considered a planet, but it was a planet for most of my life, so I still count it
In 5th grade i had to do the stupidest project on planets. Making one of those mobiles with 2 hangers and all 9 planets on it. Pluto is a planet and will always be a planet imo.
