Well-known exoplanet researcher Dr Michel Mayor ( discoverer of Peg 51b with Dr Didier Queloz in 1995 ) today announced the discovery of the lightest exoplanet found so far. The planet, “e”, in the famous system Gliese 581, is only about twice the mass of our Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist:

I will charitably assume that the reporters left out the bolded part: 2nd smallest exoplanet discovered by radial velocity variations.
I count at least 5 smaller exoplanets, one of which was discovered by radial velocity variations. |
