James Webb Space Telescope notches 1st rocky planet confirmation

"Given these possibilities, LHS 475b "very well could be an airless body that has lost any atmosphere that it once had," Lustig-Yaeger said. "But it also might possess a compact atmosphere that we are not sensitive to."

Important point to keep in mind.

https://forums.space.com/threads/astronomers-find-2nd-earth-planet-in-intriguing-alien-solar-system.59521/ has some discussion on earth size exoplanets and LHS 475 b too. The exoplanet.eu site indicates calculated temperature 586 K, water boils at 373 K. This could be a very hot almost earth-size exoplanet.
