TOI-561 b

Orbiting TOI-561 | 85.8 parsecs away

Share

TOI-561 b is a Super-Earth exoplanet (a planet larger than Earth but smaller than Neptune), about 1.4 times the radius of Earth. Its scorching equilibrium temperature of 2319 K (2046°C) makes it far too hot for liquid water. Despite its name, Super-Earths are not necessarily habitable; the term refers only to size. The planet completes one orbit around its star every 10.7 hours. It was discovered in 2020 using the transit method. It orbits the star TOI-561, located approximately 86 parsecs (280 light-years) from Earth.
