Betelgeuse is listed as the brightest star in the constellation of Orion, but it only actually attains this rank when it is at one of its rare peaks in brightness, when it can reach almost zero magnitude. Most of the time it is appreciably dimmer than Rigel (Beta Orionis) and the two stars can easily be seen to be of different colours. Betelgeuse's reddish hue is due to it being a well-developed red giant star. The star's outer layers have expanded to such a degree that if it were where the Sun is, Earth would actually be inside it. When Betelgeuse finally uses up all its hydrogen fuel, the outer layers will be cast out from the main star which will then explode as a supernova. This event could happen any time in the next million years or so.

Betelgeuse is not an important system in Frontier, being too far away from the core systems and having no life-supporting planets.
