Solakku is the star at the centre of the avali home system. It is chemically peculiar and roughly classifiable as an A-type main-sequence star. It orbits the galactic enter at a distance of 8200 light-years on average and is approximately 6.4 astronomical units (960,000,000 km) away from Avalon. This corresponds to about 53 light-minutes.
Solakku forms a binary solar system together with its red dwarf companion Crest. Alone, Solakku contains 91.29% of the total mass of this system and together with Crest, the two stars hold 99.77% of the total mass.
Like other main-sequence stars, Solakku produces energy through nuclear fusion of Hydrogen into Helium and emits most of this energy through light, in its case mostly visible light and infrared.

Formation
Solakku formed approximately 2.6 billion years ago through gravitational collapse of a molecular cloud, beginning its life cycle. This occurred most likely at the same time as Crest’s formation, as they are projected to have very similar ages. However, Crest does not share Solakku’s chemical peculiarities, so the two stars may have formed in different regions of their molecular cloud. Another theory posits that Crest was captured by Solakku and the overlapping ages are merely a coincidence.
