Hgfta-D2a

Hgfta-D2b is the moon of Hgfta-D2 and is rather similar to that of Luna. Its surface is black and does not reflect light, leading Ftopians to believe that it is a hole in the stars rather than a moon, as it is invisible during the day. This has given it its name, Nonon'totip (sky-hole in Tepingím).
