TOI-172 b is a Gas Giant exoplanet (a massive planet composed primarily of hydrogen and helium), about 10.8 times the radius of Earth. Its scorching equilibrium temperature of 1198 K (925°C) makes it far too hot for liquid water. The planet completes one orbit around its star every 9.5 Earth days. It was discovered in 2019 using the transit method. It orbits the star TOI-172, located approximately 343 parsecs (1118 light-years) from Earth.
