About this world
TOI-2096 b is an Earth-sized planet orbiting TOI-2096, a cool red dwarf (type M4) 158 light-years from Earth. It is about 1.2 times the size of Earth. It completes an orbit every 3.12 days at 0.025 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 445 K (172 °C): far too hot for liquid water on its surface. By the "cosmic shoreline", its star has probably stripped its atmosphere away, leaving bare rock.
It was discovered in 2023 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction. TOI-2096 has 2 known planets; the others are TOI-2096 c.
