TOI-178c is a potentially rocky planet that orbits the K-type star TOI-178, 204.4783 light-years from Earth.[1] TOI-178c's radius is 1.669 x that of Earth, and its mass is 4.77 that of Earth's, making TOI-178c a super earth. TOI-178c mass was discovered by the radial velocity method with the radius detected by the primary transit method.[2] The orbital radius is 0.037 AU, with an eccentricity of 0.0. A year on TOI-178c is 3.2 days long. TOI-178c was discovered by using the transit method in 2021. TOI-178b, TOI-178d, TOI-178e, TOI-178f, TOI-178g are all in the same system as TOI-178c.[3] The temperature on TOI-178c is 873 Kelvin; the hottest point longitude unknown.[2]
