Kallis III

Kallis III is a terrestrial planet in the developing [Kallis system](https://robertsspaceindustries.com/galactapedia/article/0Ql43d1nrv-kallis-system) that shares an orbit with another planet, [Kallis II](https://robertsspaceindustries.com/galactapedia/article/Rz2mZOo5zZ-kallis-ii). More massive than its sibling planet, it is also accruing matter at a higher rate, and is expected to continue increasing in size. Observing scientists believe that it may one day grow large enough to subsume Kallis II.
