According to a study published by an international group of scientists in the journal Nature, the nearest star to the Sun Proxima Centauri b exoplanet discovered Proxima.
Proxima b is in the habitable zone of its star, the surface of the exoplanet can be water, scientists believe. According to their findings, Proxima b may be closest to our solar system with a planet suitable for life. Its location could provide an opportunity for “further study by high resolution spectroscopy in the next decade, and perhaps robotic exploration in the next century,” quoted the findings of scientists TV channel CNN.
“The good news is that it is so close. It is a dream for astronomers, if you think of further studies,” says one of the study’s authors Ansgar Reiner.
Proxima b is at a distance of 4.2 light years from our Solar system, this distance is equal 266000 distance between the earth and the Sun, which are in 92,96 million miles from each other. Previously installed exoplanets, as, for example, ultracool constant, located in the star system of a red dwarf TRAPPIST-1, located at a distance of not less than 40 light-years from us.
“It is not only the closest of exoplanets detected, it is probably the closest planet outside the solar system that will ever be found, because there is no star closer to the solar system than this,” said the study’s lead author Guillem Anglada-Escude.
Proxima b is a planet with a rocky surface, it is 1.3 times heavier than Earth, orbits around Proxima Centauri with a period of 11.2 days and is at a distance of 0.05 astronomical unit (7.5 million kilometers) from her. Despite its proximity to the star, Proxima b — potentially habitable, since Proxima Centauri is a red dwarf, its surface temperature is two times lower than solar, and the mass is ten times less.
