Gup
From Kerbal Space Program Wiki
Gup would have been a small outer moon of Gurdamma.
Origins
Since Gup is far out from Gurdamma, it may be a large piece of ejecta thrown out into a highly elliptical orbit after the assumed analog collision of the Earth-Theia Collision.
Known Information
Due to the Kerbal nomenclature of small moons and asteroids being having short, simple names, Gup might be a small moon similar to Gilly, Pol, Bop, Minmus, or the new asteroid Skutt.
Due to Gurdamma being a Proto-Kerbin analogue, Gup may be a proto-Minmus.
