[2][3] It was the first extrasolar planet to be confirmed by the James Webb Space Telescope.

[6][7] It completes an orbit around its star in about 2 days and is most likely tidally locked.

[6][8] As it is very hot, with a temperature of 313 °C, if clouds are detected on its surface, this could suggest that LHS 475 b is similar to Venus, which has an atmosphere made up of carbon dioxide surrounded by thick clouds.

[6][9] On August 31, 2022, the James Webb Space Telescope's NIRSpec instrument captured the exoplanet with just two transit observations and observed its transmission spectrum.

Confirmation of LHS 475 b by the James Webb Space Telescope was published on January 11, 2023.
