Six of the newly found planets are several times bigger than Earth, increasing the population of so-called super-Earths by more than 30 percent. Most planets discovered so far are far bigger, Jupiter-sized or even larger.

 

Two of the newly discovered planets were as small as five times the size of Earth and one was up to five times larger than Jupiter.

This is amasing, please can you explain in details the certainty of this information?

This is old news, from October 2009, have you tried searching for it with Google?

Really?

May I recommend interested persons refer to The Extrasolar Planets Encyclopedia Site. As of today there are four hundred and sixty four planets listed.
