NASA’s TESS exoplanet found, which is 23 times heavier than Earth

 Спутник НАСА TESS нашел экзопланету, которая в 23 раза тяжелее Земли

NASA satellite to search for Earth-like planets outside the Solar system TESS (Transiting Exoplanet Survey Satellite) is the third exoplanet discovered during his work, according to the NASA website.

“Sputnik TESS found three confirmed exoplanets outside our Solar system for the first three months of observations,” – said on the website,reports RIA Novosti.

According to NASA, discovered the planet HD 21749b three times larger than the Earth in size and is 23 times heavier. It is every 36 days revolves around the dwarf star HD 21749 entries of class K, which lies 53 light-years from Earth in the constellation Grid. The temperature on its surface reaches 150 degrees Celsius.

“This planet has a density greater than that of Neptune, but it is not rocky,” said researcher Diana Dragomir.

According to the Guardian, the planet is likely a gas.The researchers claim on the possible discovery of another planet, which corresponds to the size of the Earth, it also revolves around the star HD 21749 entries every eight days. If its existence will be able to confirm, it will be the smallest planet discovered by TESS.About the discovery of the first planet reported on 19 September. In the message it is called “super-Earth” orbiting the star PI table mountain in the constellation of table mountain at a distance of about 60 light years from Earth. According to NASA, the mass and radius of the planet indicate a density comparable to the density of water, which allows to make a conclusion about the possible presence of water or gases. This is one of two known planets in this system.Later, on September 21, the satellite detected the second two days of the planet, worthy of scholarly attention. This planet, the size of which is slightly larger than the size of the Earth revolves around the LHS 3844, dwarf star class M 49 light years from the Earth every 11 hours. Discovery described as “hot Land”.

The apparatus of the TESS (Transiting Exoplanet Survey Satellite) NASA called the “hunter planet” and hope that it will be “a new step in the search for planets outside the Solar system, called exoplanets”. It launched in April 2018. According to the creators, TESS will explore nearly 200 of the thousands of stars near the Sun. Scientists hope that data from the device will clarify and significantly increase the number of known exoplanets and will provide the basis for future research.New camera moving in a highly elliptical orbit, about two years will “scan” the space, observing through your camera for the brightest stars. The probe and the space telescope “Kepler”, to watch the glow of the stars, locking them on the disk for the periodic dimming that indicates the passing before them of other cosmic bodies. the Probe will make a revolution in orbit every 13.7 per day, the data transmission will occur during its approach to Earth. Although the probe will not search for life on other planets, he collected data will help to determine the planet on which it is potentially possible.

According to NASA, TESS will observe practically the entire sky, covering 350 times more space than the space telescope “Kepler”. In the development of the mission satellite and the creation of the apparatus involved more than ten universities and research centers around the world.
