The Webb telescope found its first planet, and it's the size of the Earth: a year lasts only 2 days

A space observatory has helped confirm the existence of an exoplanet that is almost identical in size to Earth and is not far from us.

Scientists have confirmed that an object that orbits a star other than our Sun is a planet that is 99% the size of the Earth. And the Webb Space Telescope helped them in this. That is, the observatory discovered its first confirmed planet, on which the year lasts only 2 Earth days, writes ScienceAlert.

Initially, the fact that a planet revolves around a red dwarf star at a distance of 41 light years from us became known to scientists thanks to the observations of the TESS space telescope. But it was necessary to know for sure whether it really exists there.

Images taken by the Webb Space Telescope helped scientists confirm the presence of a rocky world, which is almost the same size as Earth.

< p>The new exoplanet, dubbed LHS 475 b, orbits a red dwarf star much cooler than the Sun in the constellation Octantus. This is a very small constellation that contains not very bright stars and can only be seen in the southern hemisphere of the Earth.

Despite being 99% the size of Earth, LHS 475 b is hotter, according to Jacob Lustig-Yaeger of Johns Hopkins University in the US. This is due to the fact that it is very close to its star and here the year lasts only 2 Earth days. That is, this planet makes a very fast complete revolution around the red dwarf.

According to scientists, despite the unique ability of the Webb telescope to see the properties of the atmosphere of other planets, there is still no exact data on the atmosphere of LHS 475 b. Scientists are generally not yet sure whether this atmosphere exists.

So far, the data indicate that if this exoplanet has an atmosphere, then most likely it is very thin and rarefied and possibly consists of methane, or maybe from pure carbon dioxide. Scientists will continue to observe this planet with the Webb Space Telescope to learn more.

Scientists believe that with this space observatory, which has completed its first year in space, it will be possible to learn much more about rocky planets that are similar to Earth.

As Focus already wrote, scientists believe that “planet factories” work in space and this explains the diversity of worlds similar to Earth.
