Nessus in Destiny 2.

Nessus is a Centaur (A minor icy planetoid) planet. It has an irregular orbit and only sporadically will be within Sol. This could be the site of limited time events.

Nessus has been fully converted by the Vex into a machine world. It possesses very unique Flora and fauna because of this. The Vanguard Scouts had catalogued this and made note of its orbit to know when it will be passing through Sol once again and the duration of its stay.
