This is the third new planet confirmed by the Transiting Exoplanet Survey Satellite (TESS) since its launch in April last year. The planet, named HD 21749b, orbits a bright, nearby dwarf star about 53 light years away, in the constellation Reticulum, and appears to have the longest orbital period of the three planets so far identified by TESS. HD 21749b journeys around its star in a relatively leisurely 36 days, compared to the two other planets — Pi Mensae b, a super-Earth with a 6.3-day orbit, and LHS 3844b, a rocky world that speeds around its star in just 11 hours
