About this world
TIC 294329732 b is a sub-Neptune orbiting TIC 294329732, a yellow, Sun-like star 618 light-years from Earth. It is about 2.1 times the size of Earth. It completes an orbit every 9.76 days at 0.086 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 824 K (550 °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 2026 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
