discovery of a new Earth-sized exoplanet orbiting a star

The team of researcherspart of the Speculoos project led by theuniversity of Liegestressed that this is only the second planetary system detected around this type ofstar After Trappist-1.r>r>>> Read also: The most distant star ever discovered is a million times brighter than the sunr>r>The planetbaptized Speculoos-3 bis “practically the same size as the Earth“, and a year on this planet, that is, an orbit around the star there lasts about 17 hours, explained the astronomer Michael Gillon of the’university of Liegeat the head of the project.r>r>”Days and nights, on the other hand, probably never end. We think in fact that the planet is in synchronous rotation, so that the same side, called the day side, always faces the star, like the Moon for the Earth, the night side would be locked in endless darkness,” he explained.r>r>Moreover, the average temperature of the star around which theexoplanet rises to 2,600°C, i.e. half that of sun. Due to its hyper-short orbit, the planet receives nearly sixteen times more energy per second than the Earth receives from the Sun and is therefore literally bombarded with radiation high energy.r>r>”In such an environment, the presence of an atmosphere around the planet is very unlikely”, punctuates Julien de Witco-director of Speculoos Northern Observatory and its Artemis telescope.r>r>”This discovery demonstrates the ability of our Speculoos-North observatory to detect terrestrial-sized exoplanets that lend themselves well to detailed studies. And this is only the beginning”, rejoiced Michaël Gillon. “Thanks to the financial support of the Wallonia and the University of Liège, two new telescopes, Orion And Apollowill soon meet Artemis on the set of Teide volcano has Tenerife (Canary Islands) in order to accelerate the hunt for these fascinating planets,” he said.r>r>Launched in 2019, the Speculoos project (Search for Planets EClipsing ULtra-cOOl Stars) aims to search for potentially habitable exoplanets (planets outside the solar system) around the smallest, coolest stars in the solar neighborhood.
