description TOI-715 b Overview
TOI-715 b is a super-Earth exoplanet discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) through the transit method. It orbits a red dwarf star located approximately 137 light-years from Earth in the constellation Volans. The planet has a radius of about 1.55 times that of Earth and resides within the conservative habitable zone of its star, meaning it could potentially support liquid water on its surface. It is a primary target for future atmospheric characterization studies using instruments like the James Webb Space Telescope.
help TOI-715 b FAQ
How big is TOI-715 b compared with Earth?
TOI-715 b has a radius of about 1.55 times Earth's radius. That places it in the super-Earth size range, although its exact composition is not established from its radius alone.
How was TOI-715 b found?
NASA's Transiting Exoplanet Survey Satellite, or TESS, found TOI-715 b through the transit method. The method measures the small dip in starlight when the planet passes in front of its red dwarf star.
Where is the TOI-715 system located?
The system is approximately 137 light-years from Earth in the constellation Volans. Its host is a red dwarf, a cooler and smaller type of star than the Sun.
Why do astronomers pay attention to TOI-715 b?
Its size and orbit around a red dwarf make it a useful target for studying small planets around cool stars. A transit also gives follow-up telescopes a chance to investigate the planet's atmosphere, if one can be detected.
