On March 4, 2014, a team of astronomers announced that analysis of new and older radial - velocity data from
nearby red dwarf stars revealed a planet with a minimum of 32 (max 49) Earth - masses at an average orbital distance of 0.97 AU from host star Gl 229, with an orbital period around 471 days (UH news release; and Tuomi et al, 2014).
On March 4, 2014, a team of astronomers announced that analysis of new and older radial - velocity data from
