NASA telescope identifies 715 planets outside the solar system

Thanks to studies carried through the Kepler space telescope, the U.S. space agency NASA has identified at least 715 planets outside the solar system.

According to results of observations obtained during the first two years since the launch of Kepler, in 2009, reveals the existence of planetary systems similar to the Solar.

Kepler is the first NASA mission whose purpose is identify extrasolar planets.

Jason Rowe, scientist at the SETI Institute in Mountain View, California, said that “the presence of several planets around a star, as with our solar system, is quite common.”

“Most planets are small compared to the scale of the planets in the solar system and, in fact, they are all in multi-systems. The 95% are smaller than Neptune,” said Rowe.
