Aster has a surface temperature of around 25 thousand Kelvin. It has an extensive debris disk. Aster's atmosphere is mostly hydrogen and helium.
== Past ==
In the past, Aster was an A-type star. 2 billion years ago it turned into a red giant, probably swallowing some of its former planets. It then became a red clump star and then an AGB star. It was becoming more and more unstable. 1.5 billion years ago, it shed its outer layers, leaving a nebula behind. After cooling down, its core transformed into a white dwarf.
== Movement ==
Aster rotates at a speed of 18 km/s. It orbits the galaxy core every 69 million years. Its orbital speed is 180 km/s. In 10 million years from now, Aster will pass by the star Starrial, at a close distance of 2 ly.
