Calri-lin
Hot planet
It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.

It is a hot planet planet with a mass one-thousandth that of K2-138, but two-and-a-half times that of all the other planets in its solar system combined.

As seen from K2-138, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
