In Astronic eschatology and in the eschatology of Astronism, stellation (and stellationism), also known as being "sent to the stars", or to "meet with the stars", refers to the process and belief respectively in which a person physically ascends to the stars upon their corporeal death (this may also be referred to as physiostellation). Stellation is also used as a collective term for a wide variety of interactions with "the stars", or The Cosmos in both Astronist philosophy and eschatology, as well as within Astronist mythology.

In the eschatology of Astronism, stellationism as a belief holds markedly less populartiy than transtellationism. To distinguish the two, stellationism affirms that when a person dies, they both physically and spiritually ascend to the stars in equal measure while in transtellationist belief, it is only our soul or spirit that ascends to the stars as our bodies are left to decompose and become one with The Cosmos physically.

In Astronist mythology, stellation takes on a range of forms, many of which are inspired by the catasterisms of Ancient Greece, also known as constellation myths.

In popular culture

There have been various instances in which the process or belief in stellation have been represented in different mediums of popular culture. A notable one of these is the central role that being "sent to the stars" holds in the story arch for the third and final English-dubbed series of Yu-Gi-Oh! GX in which duelists who lost were sent to the stars as an euphemism for their death to make the show suitable for children.
