Name: Dermun

Designation: Kaywell Ad I 2

Discovery (Mesbin): Naked Eye Object.

Derbin's largest satellite (arguably a sub-satellite or "moonmoon"), Dermun was long considered an enigmatic mystery. What secrets might Derbin be hiding on that tantalizing greenish-brown disk which can barely be resolved by Kerbal eyes? Telescopes have revealed at least a partial answer: Dermun turned out to be at least superficially similar to Graymun, with cratered highlands and flatter "ocean-like" lowlands. Perhaps by studying Dermun and Graymun together, insights may be gained about the entire Mesbin-Derbin system! On the other hand, the greenish tint is suspicious when compared to Derminmus. It may be worth checking if there's mint or perhaps pistachio flavoring here, too.
