Astronomers Find Youngest Exoplanet Yet | Est 35M years old, 83 light years away | Universe Today - http://www.universetoday.com/2010...
"Overcoming interference from a very active young sun-like star, a group of astronomers were able to find what they determined is the youngest exoplanet yet discovered. BD+20 1790b is 35 million years old (Earth is about 100 times older at 4.5 billion years) and is located about 83 light years away from our planet. Previously, the youngest known exoplanet was about 100 million years old. Studying this planet will help our understanding of planetary evolution." - Kurt Starnes
