The discovery of a planet smaller than Earth very close to complete its orbit in just 8 hours

Astronomers from the Planetary Research Institute of the German Aerospace Center have discovered a terrifying planet: smaller than Earth and so close to its star that it completes its orbit in just eight hours, its host star, which is relatively close to it at a distance of 31 light-years, and it is an even smaller and more massive red dwarf. Cooler than our sun, according to a digitaltrend tech report.

But even so, the planet is so close that its surface temperature can reach 2,700 degrees Fahrenheit, and the planet is bombarded with radiation more than 500 times stronger than the radiation found on Earth.

Named GJ 367 b, the planet is smaller than most of the exoplanets discovered so far, which tends to be comparable in size to Jupiter, and is only half the mass of Earth but slightly larger than Mars with a diameter of 5,500 miles.

It was discovered using NASA’s Transiting Exoplanet Survey Satellite (TESS), a planetary researcher who discovers planets using the transit method, as it monitors light from distant stars to look for dips in brightness caused by a planet moving between the star and Earth.

After its discovery with TESS, GJ 367 b was further investigated using the European Southern Observatory’s 3.6m telescope, a ground-based telescope that uses a different method to more precisely determine its radius and mass.

Principal researcher Christine Lamm explained: “From the precise determination of its radius and mass, GJ 367 b has been classified as a rocky planet, and appears to have similarities with Mercury. Second Earth.

However, despite its similarity to Earth, you wouldn’t want to go to GJ 367 b. Its surface temperature is so hot that it can almost evaporate iron, and the researchers think the planet may have lost its entire outer layer, called its exosphere.

But studying the planet can help astronomers learn more about how planets and planetary systems form, which may help us understand more about the evolution of our planet and our solar system.

And when it comes to planets orbiting this close to their stars, called very short-period planets (USPs), “we already know quite a few of these planets, but their origins are currently unknown,” Lam said, “by measuring the exact basic properties.” For Planet USP we can get a glimpse into the history of the formation and evolution of the system.”
