294.5 trillion kilometers away. A number that is hard to imagine describes the distance to the nearest possibly habitable planet. “” GJ 357 “”, the awkward name, has been discovered by an international team of astronomers who are now looking for further signs of life.

“” It’s exciting because this is the first super-earth in the vicinity that could harbor life, “said Austrian astrophysicist Lisa Kaltenegger, who was involved in the analysis.

Although proximity is relative here, the star in question GJ 357 is 31 light-years (that is, about 294.5 billion kilometers) away from Earth and can be found in the constellation Water Snake (Hydra). The find was made possible by NASA’s Transiting Exoplanet Survey Satellite (Tess). With its help, the scientists came across an exoplanet in February 2019, which partially covers GJ 357 in its orbit, thereby weakening its light.

A total of three exoplanets

This planet, called GJ 357 b, turned out to be about 22 percent larger than the earth and orbits its star eleven times closer than the planet Mercury, the closest planet to our central star. The temperature at GJ 357 b is estimated at 250 degrees Celsius. “” We call GJ 357 b the so-called hot earth, “explained Stefan Dreizler from the Institute for Astrophysics at the University of Göttingen. “” Although the planet cannot harbor life, it is an important milestone in the exploration of Earth-like planets. “”

The research team headed by the Institute for Astrophysics of the Canary Islands on Tenerife was able to confirm the existence of GJ 357 b. This was achieved with the help of ground-based data, recorded since 1998 at the European Southern Observatory and the Campanas Observatory in Chile, as well as at the Keck Observatory in Hawaii and the Calar Alto Observatory in Spain.123helpme The results have now been published in the journal “” Astronomy Astrophysics “”.

Surprisingly, the scientists subsequently came across two more exoplanets, which were given the names GJ 357 c and GJ 357 d. While GJ 357 c is in all probability very hot and has at least 3.4 times the mass of the earth, the outermost known sister planet of the system – GJ 357 d – could offer conditions like on earth, according to a broadcast by the Tess team on Wednesday.

Looking for signs of life

GJ 357 d is likely to orbit the dwarf star every 55.7 days at a distance of about 20 percent of the distance between the earth and the sun. The scientists assume that its mass is at least 6.1 times that of the earth. “With a dense atmosphere, the planet GJ 357 d could hold liquid water on its surface like the earth,” “said Kaltenegger. He is “” one of the best planets “” to look for signs of life with future telescopes.

The Austrian, who conducts research at Cornell University in Ithaca (US state New York) and is part of the scientific team of the Tess mission, simulated the possible conditions on the planet in cooperation with PhD student Jack Madden and his fellow student Zifan Lin. This could have a rocky composition, but it could also be a water world, as reported in the specialist journal “The Astrophysical Journal Letters”. If GJ 357 d is a rocky world, its size would be between one and two times the size of the earth. GJ 357 d receives approximately the same amount of energy from its central star as Mars does from the sun.
