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:

Of minor importance perhaps, yet more observations have revealed that Trappist 1h orbit the central star each 18.764 days, a value near what what predicted.
The radius turned out to be 0.715, while the calculated temperature at 169 K would make it a very cold world, which again is in line with predictions. A terrestrial-sized exoplanet at the snow line of TRAPPIST-1 Some datasets seen on Astrobiology web And a Youtube film where 'Universe sandbox' is used, even though it's probably not a fully reliable model.I think he get quite close to the mark there. |
