Gliese 1132, 41 light years away, has two planets of which we know. The innermost one transits with respect to Earth line-of-sight. Now, there's news of its atmosphere.
The planet is on an ellipse so endures tides... in its rock. Its temperature is conjectured 256 C.
The atmo is hydrogen, hydrogen cyanide, methane, and smog. They think it used to be a Neptune but, being close to the star, lost its original atmosphere both outward and inward. That hydrogen is thought to be from its original atmosphere, sucked into the magma and now being outgassed again.
The gravity and the heat of its interior are such that it likely doesn't have mountains. Cracked plains and lava-pools, here. If this was attainable from the game Starflight it would be a Molten World.
Lovely place. All the worst features of Neptune, Titan, Io, and Venus.
