Kulos, the third planet orbiting Sirius A, lies just inside Sirius B's closest approach to the larger star; its 2.5-Earth-year orbit is in 20:1 mean motion resonance with Sirius B, and when Sirius B is at its closest point, Kulos is at the closest point in its orbit. Nonetheless, it remains locked in stable orbit around Sirius A.
The temperature on Kulos ranges from "too hot" to "much too hot". The stats given here are for aposir (Sirius B's furthest point), and the `TMP` and `RAD` rise to 8 during closest approach.
