Orbiting HAT-P-46 | 290.7 parsecs away

Share

HAT-P-46 b is a Gas Giant exoplanet (a massive planet composed primarily of hydrogen and helium), about 14.4 times the radius of Earth. Its scorching equilibrium temperature of 1458 K (1185°C) makes it far too hot for liquid water. The planet completes one orbit around its star every 4.5 Earth days. It was discovered in 2014 using the transit method. It orbits the star HAT-P-46, located approximately 291 parsecs (948 light-years) from Earth.
