We report the detection of a new candidate exoplanet around the metal- rich star 1 Gruis. With M sin i = 1.23±0.18 MJUP, a period of 1326±300 d and an orbit with an eccentricity of 0.14±0.14 it adds to the growing popula- tion of long period exoplanets with near-circular orbits. This population now comprises more than 20% of known exoplanets.
