"Super-Earth" has discovered the orbits closest to the Sun Star


Astronomers have discovered a frozen planet with a mass more than three times larger than Earth, which circles the nearest solitary star to the Sun. A potential rocky planet, known as Barnard's star b, is a "super-earth" and orbit around its host star once every 233 days, researchers from Queen Mary University in London in the United Kingdom said.

The findings published in the Nature magazine show that the planet lies in a remote region from a star known as the "snow line".

This is well beyond the living area in which there could be running water and possibly life, researchers said.

It is estimated that the planet's surface temperature is around minus 170 degrees Celsius, which means that it is probably a frozen world that will not be inclined to a life similar to Earth.

However, if the planet has a significant atmosphere, the temperature could be higher and the situation more potentially more hospitable.

"Barnard's star is a notorious object among astronomers and exoplanet scientists, since it was one of the first stars in which the planets were originally established, but later turned out to be wrong. Hopefully this time we got it right," said Guillem Anglada Escude from Queen Mary College for Physics and Astronomy.

After nearly six light years, Barnard's star is the next closest star to the Sun after the triple Alpha Centauri system.

It's a kind of bad, low-fat star called the red dwarf. Red dwarfs are the best places to find candidates from ecoplanets that are planets outside our solar system.

Barnard's star b is the second closest known exoplanet of our Sun. The nearest is just over four light years from Earth.

This explane, called Proxima b, circles around the red dwarf star Proxima Centauri.

The researchers used a radial velocity method between observations that led to the discovery of Barnard's star b.

This technique detects the vibrations in the star, which are probably caused by the gravitational pull of the planet around the circle.

These lumps affect the light that comes from the star.

When the star moves towards Earth, its spectrum changes slightly in the blue direction and moves towards the red.

This is the first time that this technique was used to detect a planet that is so small so far away from its host star.
