Suggested nameYisherx You
Planet typeHot planet
The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to Kepler-1818, which reoccurs over the so-called synodic period approximately every 139 days.

As seen from Kepler-1818, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.

It may have had carbonyl sulfide oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
