A planet almost the same size as the Earth was discovered - voila! technology


The star, K2-415b, was detected thanks to observations by the TESS space telescope, and is located 72 light-years from Earth - a fairly short distance by astronomical standards

An international team of researchers has found a new Earth-sized moving exoplanet, named K2-415b, located just 72 light-years away from us.

The researchers identified the extrasolar planet in data from NASA's Kepler space telescope, and its successor, the TESS space telescope. According to the researchers, on an astronomical scale, K2-415b is one of our closest neighbors. K2-415b orbits a tiny star, a red dwarf

, K2-415 is its name. According to an international team of astronomers from the Center for Astrobiology in Japan, the option to look at stars of this type up close may help researchers better understand their atmospheric conditions that "could in the future become habitable."

Unlike our sun, red dwarfs are much cooler and smaller.

The first measurements showed that the red dwarf of K2-415b has a surface temperature of about 2,900 Kelvin compared to the Sun's 5,480 Kelvin.

So far, only 4 stars with similar characteristics have been discovered and among them is the Trappist-1 system, a very cold dwarf located 39.13 light years from Earth.

Initial estimates indicate that the planet is about three times as massive as Earth, although it has a radius only 1.015 times that of Earth.

However, the researchers estimate that the star does not contain liquid water due to its proximity to its red dwarf, but are still optimistic to find a star in the region that may indeed resemble our Earth.

K2-415b, as the extrasolar world is called, orbits the red dwarf star K2-415 and was identified thanks to data from NASA's Kepler and TES telescopes. K2-415b is of particular interest to scientists because of its star: although it is one of the coldest and low-mass Relatively speaking, it is capable of hosting a planet. So far only 4 stars with similar characteristics have been discovered and among them is the famous Trappist-1 system which boasts seven worlds in orbit.
