 Not to be confused with Asteroidian. Astroidian also known as Adonic describes a MLNB or a man who loves non-binary people, this attraction can be exclusive or not. Asteroidian is an umbrella term like achillean. It was intended for men who are dating non-binary people, but those that attached to non-binary people anyways can also use it.

The term was coined by Tumblr user Orbisian-Prinxess, who is now deactivated. It was coined on discord, so it's unknown when exactly it was coined, but it likely happened sometime in early 2018. The flag was also designed by Orbisian-Prinxess, it has a meaning however that is unknown due to the fact that the blog is deactivated.

Etymology
Asteroid comes from the Greek word for star. Non-binary people are often represented by stars (such as with stellarian) as there are countless stars completely separate from the influence of our human gender binary (unlike the sun and moon, having been gendered in religions and cultures through time), loving non-binary people as a man is known as being an astroidian, especially as men are represented by squares, and the shape of an asteroid is square-like yet also star like, representing the union of men and non-binary people.
