They find in the archive of the Kepler telescope the planet most similar to Earth – La Provincia

Reanalyzed data from the space telescope Kepler of the POT have revealed a exoplanet the size of the land that orbits in the habitable zone of your star, the area around a star where a rocky planet could support liquid water.

Scientists discovered this planet, called Kepler-1649c, when examining the old Kepler observations, which the agency withdrew in 2018. While previous searches with a computer algorithm misidentified it, researchers who reviewed Kepler’s data looked at the signature again and recognized it as a planet. Of all the exoplanets found by Kepler, this distant world, located 300 light years from Earth, it is the most similar to the size and estimated temperature of Earth.

This newly revealed world is only 1.06 times bigger than our own planet. Also, the amount of starlight it receives from its host star is 75% of the amount of light the Earth receives of our Sun, which means that the temperature of the exoplanet can also be similar to that of our planet. But unlike Earth, orbit a red dwarf. Although none have been observed in this system, this type of star is known to stellar shoots that can make a planet’s environment challenging for any potential life.

“This intriguing and distant world gives us even greater hope that a second Earth is among the stars, waiting to be found,” it said in a statement. Thomas Zurbuchen, Associate Administrator of the NASA Science Mission Directorate in Washington.

There is still much unknown about Kepler-1649c, including its atmosphere, that could affect the planet’s temperature. Current calculations of planet size have significant margins of error, as do all values ​​in astronomy when studying such distant objects. But according to what is known, Kepler-1649c is especially intriguing for scientists looking for worlds with potentially habitable conditions.
