Tau Ceti e, also called 52 Ceti e, is an unconfirmed
HARPS.[1][2] Its possible properties were refined in 2017, where it was one of two planets recovered from new data, the other being Tau Ceti f. It would orbit at a distance of 0.552 AU (between the orbits of Venus and Mercury in the Solar System) with an orbital period of 168 days and has a minimum mass of 3.93 Earth masses.[3] If Tau Ceti e possesses an Earth-like atmosphere, the surface temperature would be around 68 °C (341 K; 154 °F).[4] Based upon the incident flux upon the planet, a study by Güdel et al. (2014) speculated that the planet may lie inside the inner-boundary of the habitable zone and be a Venus-like world.[5]
