Scientific observations collected over a 20-year period suggest that there could have been a dark, semi-opaque planet called "Giant Earth" orbiting the nearest star of our solar system, said Falcone.
The planet, estimated at more than 3.2 times the size of the Earth, gravitates around the star Bernard, a star to the cold mass of the so-called red dwarf. The star is about six light years from the solar system, which is relatively close to astronomical standards. The planet is believed to cycle around the star Bernard every 233 days.
It has already detected nearly 4,000 planets outside the solar system. The planet is the second planet closest to our solar system to be discovered. It is thought to be a "Giant Earth", a group of planets larger than the Earth but smaller than the gaseous planets. Ignacy Ribas, researcher at the Catalan Institute for Space Studies.
"After a very thorough analysis, we are 99% certain of the existence of the planet," said the space science institute in a statement. But we will continue to monitor this fast-moving star to exclude any natural changes that are not possible in the degree of brightness that may resemble the planet. "
The only stars closest to the star Bernard are the three-star Alpha Centauri system, located just over four light-years away from our solar system.
About two years ago, astronomers announced the discovery of a planet the size of the planet revolving around the star Proxima Centauri, one of the stars of this tripartite system located at a distance that allows the water to be present in the liquid state on its surface, thus increasing the possibilities of life. The planet detected around the star Bernard might not have life because the temperature on the surface of it could reach 274 degrees Fahrenheit below zero (170 degrees Celsius below zero). The frozen planet of the star Bernhard only reaches two percent of the energy transmitted by solar radiation to the planet. The researchers studied the planet by combining the measurements of several high-resolution instruments with telescopes from around the world.
