1. Only planet to spin opposite of others
2. Extremely little H20
3. No moon(s)
You are correct that Mercury and Venus have no moons. That's one clue nailed and only two more to go.
Mercury has a curious spin ratio to its oblong loop around the sun every 88 days, so the part mostly in "night" keeps down below 100 degrees near the poles, and moisture doesn't boil away.
You've narrowed the field considerably, and I believe the next answer will win the coveted next turnie.
Byrdie was six minutes ahead of Angel -- not much in astronomical time, but enough for Washinton state to recapture the Trio Trophy.
Astoria, Oregon?
Your turn!
PS. I am suprise that Chase didn't guess at it!
After no guesses on the first three clues for 24 hours, so here are three more:
4. TV series
5. One star played the head elf in The Santa Clause
6. Go figure!
Cheetar
Third Earth

My girlfriend's grandson says it's about Power Rangers, and the black cat villain. Close?
