TOI-813 (also known as TIC 55525572 [5] and 2MASS J04504658-6054196) is a bright subgiant G-type star [6] located 858 light-years (263 parsecs) away from planet Earth. It is too faint to be seen with the naked eye. TOI-813 has a mass of 1.32 solar masses, a radius of 1.95 solar radii and a luminosity of 4.3 times the solar luminosity. [7]
The star has one known exoplanet orbiting it named TOI-813 b, a Neptune-like gas giant. [7]
