VY Canis Majoris

VY Canis Majoris is the largest known star in the Milky Way Galaxy. It is a hypergiant 3,900 kilometers from Gaea and has a radius of 1,975,000,000 kilometres.

Physical characteristics
VY Canis Majoris is so large that if placed in the Sol system, it would extend as far out as Saturn. It is an aged, dying star that is expected to explode into a magnificent hypernova sending gamma bursts nearby. While Gaea will not be affected, Ucharpli and Delse will be destroyed by such an event.

The star is surrounded in an enormous circumstellar nebula simply known as Canis Major. Because this nebula is surrounded by warm, radiation filled gas, it is almost impossible to navigate. While minor planetoid bodies within this nebula, very little of it has been explored.

Dimonroff
Around 5 AU from the star is a facility known as Dimonroff, a secret location used for research beyond galactic law. The remoteness of this star as well as the obscurity of the nebula makes it almost impossible to find.
