Saturnian is a non-binary xenogender in the celestial gender system.
Under the rework of the celestial gender system, saturnian is also known as merlunettian. It is defined as someone who is lunettian and mercurian. One could be both at the same time or they might be fluid between the two. They may feel different amounts of each gender at different times. Under the rework the original definition of saturnian is now included with venusian.
History
The term saturnian was coined by the Tumblr blog Uncommongenders in November 2, 2017[1]. However the definition of many of the celestial genders were altered in a rework by Tumblr user System-Lgbt reworking the system, to make it more consistent[2].
The original flag was posted by the user Juparian on November 7, 2017[3]. The color pallet was requested by Uncommongenders, the coiner of the term. Both the old and new flag were based on the colors of Saturn.
