Thetis

Thetis is an asteroid in the Sol Asteroid Belt. Thetis is the site of the Thetis Aquacultural Center of the Sol Asteroid Belt Colonies.
First discovered in 1852 AD, Thetis is an S-type asteroid. When establishing an aquacultural center in the Sol Asteroid Belt, Thetis was chosen since it has no significant resources of any other value.
Thetis has been mined out and domed over in the centuries since its establishment and is famed throughout the Sol Asteroid Belt Colonies and the Sol System itself as a producer of fresh aquacultural products.
