23 Dec 2011: Tha semi-majors axis is derived from the stellar radius and the ratio a/Rs given by Fressin et al. 2011. The semi-major axis derived the the stellar mass and the orbital period is 0.064 ± 0.001 AU.
21 Dec 2011: The mass limit is derived from RV measurements; "theoretical considerations give 0.39 MEarth < MP < 1.67 MEarth" (Fressin et al 2011)
