NASA's TESS exoplanet hunter has found its first planet at earth size, but you do not want to visit it – BGR



NASA's TAS Exoplanet Hunting Telescope has been in operation for less than a year, but has already made some impressive discoveries. After announcing a new "Hot Saturn" in March, NASA just revealed that TESS had found its first planet-sized planet outside of our solar system.

TESS – which stands for Transiting Exoplanet Survey Satellite – is intended to detect the telltale signs of exoplanets orbiting the stars, recognizing the tiny changes in brightness associated with a planet passing by. This latest observation is actually the 10th confirmed planet that TESS has discovered, but it is the first one that is likely to be in size in size. Still, you definitely would not want to go there.

The earth-sized planet HD 21

749c is estimated at about 89% of the earth and orbits a star that is about 70% the size of the Earth's sun. The relationship between the planet and its star, however, is little earth-like. The discovery is described in detail in a recent article, Astrophysical Journal Letters .

One year on the planet takes less than eight days on Earth, suggesting that it is incredibly close to the star. This close relationship means that HD 21749c is absolutely hot, and researchers estimate that its surface is likely to be 800 degrees Fahrenheit or 427 degrees Celsius.

The planet and its star are not very far away. It is believed that HD 21749 is only about 53 light-years away, which means that it is possible to study it and its hot planet in more detail.

HD 21749c is not the place we've ever been Expect to find life the way we know it, so alien hunters must search elsewhere, but the discovery of a planet outside our solar system is still interesting. It is expected that new exoplanet discoveries will be continued by TESS, so that NASA may not find a world like ours for much longer.
