Super-earth discovered orbiting the sun’s famous stellar neighbor

Bone-crushingly cold Super Earth discovered orbiting nearby star

ASTRONOMERS have discovered a frozen "super-Earth" orbiting the closest solitary star to the Sun, a breakthrough that could shine light on our planet's nearest planetary neighbours.

Flashback: The exoplanet is the second closest known exoplanet to Earth, CNN reports.

This was reported in the journal Nature.

"The biggest "kick" about this discovery is the host star", Paul Butler, study co-author and astronomer at the Carnegie Institution for Science, told CNN.

Ribas said that although stargazers could predict its size and orbit with relative accuracy using the Doppler effect, any attempt at this stage to find out what the new planet looked like would be "guesswork". But, because Barnard's Star is so dim, the potential planet lies right around the system's "snow line" - the region where volatile materials such as water can condense into solid ices. "However, we will continue to observe fast-moving star, to avoid possible, but unlikely, natural variations in star brightness that could be mistaken for caused by the planet".

In a landmark discovery, an global team of astronomers led by Ignasi Ribas of the Institute of Space Studies of Catalonia (IEEC) and Institute of Space Sciences (IEEC- CSIC) has found a candidate planet orbiting Barnard's star. The probably rocky planet, designated Barnard's Star b, is likely extremely cold (-274F) and very dark because it only gets two percent of the energy from its parent star that we get from our radiant sun.

Barnard's star appears to move across the Earth's night sky faster than any other star.

"After very careful analysis we are 99 percent sure that the planet does not end there - says a leading research scientist Ignasi Ribas". Only the Alpha Centauri triple system is closer.

This planet is revolving round a dwarf star that the scientists named Barnard which is also known as a "Red Dwarf" and is one of the nearest to our sun. "Follow-up observations are already underway at different observatories worldwide".

Is this planet really, though?

One light year is equal to the distance travelled by light in one year so any visible light from the newly discovered planet is six years old. "However, we must remain cautious and collect more data to nail the case in the future". "This is the result of a large collaboration organized in the context of the Red Dots project, which is why it has contributions from teams all over the world including semi-professional astronomers coordinated by the American Association of Variable Star Observers".
