Ceresian is a non-binary xenogender in the celestial gender system. Is a gender that is both plutoian and lunettian. Someone who is ceresian could feel both genders at the same time, feeling a connection to both soft feminine celestial energy as well as a connection to the void. Or they may be fluid between the two. They may feel different amounts of each gender at different times. Ceresian can also be considered the demigender form of lunettian.
History
The term ceresian and the flag were created by Tumblr user Juparian on December 31, 2017[1]. However, when the term was coined is originally referred to "a combination of juparian and mercurian". The definition of many of the celestial genders were altered by System-Lgbt is a rework of the system, to make it more consistent[2]. Neptunian now means what ceresian used to mean. The colors of the new flag are based on the colors of the dwarf planet Ceres.
