MADRID (AFP) - Spanish astronomers Wednesday announced the discovery of the smallest planet discovered to date outside the solar system, located 30 light years from earth.
The planet, "GJ 436T", was detected through a new technique which "will allow us to discover in less than 10 years the first planet resembling earth in terms of mass and orbit," said Ignasi Ribas of Spain's CSIC scientific research institute.
It was discovered by a team led by Ribas through its gravitational pull on other planets already discovered around the same star in the constellation of Leo.
