Two earth-like planets discovered 12.5 light years away

Space scientists have discovered two earth-like planets revolving around a nearby star which seems to be near yet far, i.e. 12.5 light years away from our galaxy.

Its surface temperature is 2,700 degrees Celsius, and its mass is only one-tenth that of the Sun, researchers said.

The discovered planets revolve around Teegarden star - a red dwarf in the direction of the constellation of Aries, according to the study published in the journal Astronomy and Astrophysics. Its surface temperature is 2,700 degrees Celsius, and its mass is only one-tenth that of the Sun, researchers said.

"We have been observing this star for three years to look for periodic variations in its velocity," said Mathias Zechmeister, a researcher at the University of Gottingen in Germany.

The observations showed that two planets are orbiting it, both of them similar to the planets in the inner part of the Solar System.

They are just a little bigger than the Earth and are situated in the 'habitable zone' where water can exist as a liquid, according to the researchers.

Photometric campaigns on this star have been carried out with the Carlos Sanchez Telescope at the Teide Observatory in Spain, and with the network of telescopes of the Las Cumbres Observatory, among others.

For the transit method to be viable, the planets must pass across the face of the stellar disc and block some of the light from the star during a short time, which means that it must lie on a line joining the Sun and the Earth.

This lucky alignment occurs for only a small fraction of planetary systems, researchers said.

The type of star to which the Teegarden star belongs consists of the smallest for which researchers can measure the masses of their planets with current technology.
