Katheynix is asteroid #49350 and also known as 1998 WQ₈. Katheynix’ orbit is characterized by a semi-major axis of 2.41 Astronomical Units, an eccentricity of 0.09, a period of revolution of 1 366 days, and an inclination of 6.9 degrees. Katheynix was discovered by the American chemical engineer and amateur astronomer Walter R. Cooney Jr. at the Highland Road Park Observatory/ Baton Rouge Observatory.

Katheynix is named after Kathey Nix, who lived on the material plane from 1953 until 2003 and was an amateur astronomer, manager of theaters for the Pink Palace Museum, Memphis, Tennessee, USA, and a founding member of the Society of Low-Energy Observers (SLO). The latter simply is a club of amateur astronomers. The name Kathey is much less frequent than its variant Kathy, so I can be sure that Kathey is easier to find by search engines and I thus can be sure that nothing else is publicly known on Kathey Nix. What caught my attention is her family-name because it makes her a namesake of Pluto II, also known as S/2005 P 2, being Pluto’s third-largest asteroid-moon. It is a spelling variant of the name of the Greek goddess Nýx (Νύξ) and the Roman goddess Nox.

Nýx (Νύξ) doesn’t represent, but herself is the night. So Kathey Nix is a mortal woman, who has the night in her name and also was active as an amateur astronomer, which usually is done at night. So Katheynix should represent nocturnal persons or indicate that a person is nocturnal.
