Solid planets outside the solar system

Brussels - European astronomers from the first rocky planet found outside solar system, like the Earth but it ruled high temperature because it is too close to their stars.

In the search for planets similar to Earth, scientists have so far discovered more than 300 celestial objects outside the solar system, but in most cases, the gaseous planets. Newly discovered planet, which has so far najsličnija Earth due to its solid structure, has one drawback - Pakleno is hot.

"It looks like the Earth, but is too close to the sun," said Artie Harces Director observatorijuma in Turingeru, Germany.

The planet, named Corot-7b, has a surface temperature higher than 2000 Celsius which is too much for the development of life. Circle around their stars make for only 20 hours, at a speed of 750,000 kilometers per hour. By comparison, Mercury, and the closest planet to our Sun completes its rotation around the sun for 88 days.

Corot-7b was discovered earlier this year. It is in our immediate neighborhood at a distance of about 500 light years. It has a radius 1.5 times larger than Earth and five times more mass.

Evroposki astronomers immediately went to his observation to determine its density, and they managed to prove that it really comes stenovitoj planet what is ours. In our system, besides Earth, circling the planet three more solid. These are Mercury, Venus and Mars.

This discovery gives scientists hope to find planets similar to Earth in space with more suitable conditions for life

"The evidence that we live in a populated universe become more convincing," said Alan Bos, an expert with the Carnegie Institute.
