Observability Predictor 
Remarks
Alias GJ 176 b05 Sep. 2008: A planet with a mass of 25 MEarth and a period of 10.24 days was claimed by Endl et al 2007. Forveille et al. 2008. show that Endl et al.'s detection is invalidated and propose a different planet with a mass of 7.8 Mearth and a period of 8.8 days.
