Gliese 367 b

[2] Due to its close orbit, the exoplanet gets bombarded with radiation over 500 times more than Earth receives from the Sun.

[4] Gliese 367 b is presumably tidally locked, and any atmosphere, if ever existed, would have boiled away due to the planet's extreme temperatures.

[4] The absence of day-night heat recirculation suggests significant volatile loss, shaping its current atmospheric and surface properties.

GJ 367b's exceptional density raises intriguing hypotheses about its origin, from mantle evaporation to Mercury-like collisions.

This discovery prompts broader inquiries into the habitability of small rocky planets orbiting M dwarfs and offers valuable insights into planetary formation and atmospheric dynamics across the cosmos.
