What about all the other KBOs out there? And why add the qualifier "Planet/moon" if there are no moons? Going back to the KBOs, Sedna easily outstrips everyone with its 13,000 year orbit. Surely that should be of some importance to this quiz?

Why is Mars 1 when it's actually 1.88 earth years (thus much closer to 2)? I legitimately though it was the earth or maybe the Moon and I didn't even think of Mars.

I am as dumbfounded as you lol, this quiz is at least 3 years old, I don't know what I was thinking when I made it.
