Ultrahard? Oh, my :-?

Let's see - Which is the "reddest" celestial body inside the orbit of Puto?

Hint: You can see it with amateur equipment.

To gain extra credit, tell us something about the mythological significance of the person after whom it was named.

I am not absoluteley sure what "reddest" refers to - probably the relative strength of the red wavelengths in the reflection spectrum of the body. I take some artistic liberty here, not being a physicist.
