Rocky-Planet

Astronomers have discovered what they claim is the smallest-ever rocky planet outside our solar system, named Kepler-10b.

A team at NASA says that its Kepler mission has confirmed the discovery of the exo-planet, measuring 1.4 times the size of Earth — its discovery is based on eight months of data collected by the spacecraft from May 2009 to Jan 2010.

According to the astronomers, the rocky planet has a mass 4.6 times that of Earth and with an average density of 8.8 grams per cubic centimetre, it’s similar to that of an iron dumbbell, the ‘Astrophysical Journal’ reported.

All of Kepler’s best capabilities have converged to yield the first solid evidence of a rocky planet orbiting a star other than our sun,” Natalie Batalha, Kepler’s deputy science team leader at NASA’s Ames Research Center in Moffett Field, California, said.
