USco1621 b is a Gas Giant exoplanet (a massive planet composed primarily of hydrogen and helium) with a mass of 5085.3 Earth masses. Its scorching equilibrium temperature of 2270 K (1997°C) makes it far too hot for liquid water. It was discovered in 2019 using the imaging method. It orbits the M-type star USco1621 A, located approximately 138 parsecs (450 light-years) from Earth.
