OGLE-2007-BLG-368Lbis anextrasolar planetlocated approximately 19,230light-yearsaway in theconstellationofScorpius,orbiting thestarOGLE-2007-BLG-368L. This planet was detected on December 8, 2009 by thegravitational microlensingby Sumi. It hasmass6.94% ofJupiter(i.e. 22 times that ofEarth) and is located 3.3AUfrom the star when observed. Based on those properties it would classify as a Cold Neptune. It is the second Cold Neptune to be observed, the first beingOGLE-2005-BLG-169Lb.[1]This planet is most likely be similar toUranusandNeptunein theSolar Systemin terms of atmospheric and internal properties.
