    It has been classed as a hot superterran.

    It was discovered by the Kepler space telescope in 2014 using the transit method and was originally classed as a planet candidate, but during a study[4] by members of the NASA Ames Research Center on two other planets in the Kepler-296 system, Kepler-296f and Kepler-296e, they were able to confirm that Kepler-296 b is an exoplanet with "more than 99% confidence".
