Rigellian
Rigellian refers to anything originating from the star Rigel, located in the constellation Orion. Rigel is a supergiant star, significantly larger and more luminous than our Sun. Due to its immense distance from Earth, direct observation of Rigel's planetary system, if one exists, is extremely challenging with current technology.
In science fiction, the term "Rigellian" is often used to denote beings or phenomena associated with Rigel.
