Artistic depiction of Tau Ceti e as a terrestrial planet.

Tau Ceti e, also called 52 Ceti e, is a possibly real exoplanet orbiting (going around) Tau Ceti. It was detected in 2012 by using tools and their data to analyze if it was a planet. It would orbit between Venus and Mercury at a distance of 0.552 AU with an orbital period of 168 days. It has a minimum mass of 3.93 Earth masses. It was featured in Project Hail Mary.
