NEW EXOPLANET IS A SECOND VENUS
THE CLOSEST ROCKY Earth-sized planet ever found could be similar to Venus. GJ 1132b is just 39 lightyears away and has a surface temperature of around 230ºC – though this is too hot for liquid water, it does allow for an atmosphere to persist.
The planet is notable as most rocky worlds discovered have surface temperatures of several thousand degrees Celsius, far too hot to maintain an atmosphere. And, being so close, it may even be possible to observe its weather patterns.
“While GJ 1132b is not in the habitable zone, every new planet teaches us more about how planets work in general. It is definitely not ‘another Earth’ but a really hot new planet,” says Lisa Kaltenegger of Cornell University. http://www.gmto.org
GJ 1132b is also tidally locked, meaning that the same side of the planet faces its parent star
