TOI-1135 b is a Gas Giant exoplanet (a massive planet composed primarily of hydrogen and helium), about 9.3 times the radius of Earth. Its scorching equilibrium temperature of 1074 K (801°C) makes it far too hot for liquid water. The planet completes one orbit around its star every 8.0 Earth days. It was discovered in 2024 using the transit method. It orbits the star TOI-1135, located approximately 114 parsecs (372 light-years) from Earth.
