Asteroid Vesta is 'last of a kind' rock
http://bbc.in/JiLdv7
Vesta is the only remaining example of the original objects that came together to form the rocky planets, like Earth and Mars, some 4.6 billion years ago. This assessment is based on data from the Dawn probe which has been orbiting the second largest body in the asteroid belt for the past 10 months. The findings from the Nasa mission are reported in Science magazine.
