TOI-715 b is a super-Earth exoplanet in the habitable zone of its parent M-type star, TOI-715. [1] [2] [3] The planet is 1.55 times larger than Earth, and is located at 0.083 astronomical units (12,400,000 km) from its star. [4] The planet orbits on the habitable zone of its star and has an equilibrium temperature of 234 K (−39 °C). [4] It was discovered by the Transiting Exoplanet Survey Satellite (TESS) in 2023; [5] according to the authors of the discovery paper, it is the first TESS discovery in the conservative habitable zone. [4]
NASA stated that the James Webb Space Telescope may be used in the future to look for evidence of water or planetary atmosphere. [6] Additionally, there may be a second exoplanet in the same system, TIC 271971130.02, that, if confirmed, would be the smallest known habitable-zone exoplanet. [6]
[W]hile several 'habitable zone' planets discovered by TESS have been confirmed (e.g. Gilbert et al. 2020; Vach et al. 2022), none yet have fallen within the conservative habitable zone as described by Kopparapu et al. (2013)—until now.
The planet, named TOI-715 b, is around 1 1/2 times the width of our Earth and is orbiting in a habitable zone around its parent star.
