Smallest Planet Yet Found Circling a Main Sequence Star (other than our sun)

~ 7.5 Earth-Mass Planet Orbiting the Nearby Star, GJ 876

"High precision, high cadence radial velocity monitoring over the past 8 years at the W. M. Keck Observatory reveals evidence for a third planet orbiting the nearby (4.69 pc) dM4 star GJ 876." ... "This inclination yields a mass for companion d of m = 7.53 +- 0.70 Earth masses, making it by far the lowest mass companion yet found around a main sequence star other than our Sun."
