Researchers spotted this planet, called Kepler-1649c, by analyzing old data obtained from NASA’s Kepler space telescope which completed its mission in 2018.
Of all the exoplanets found by Kepler, this distant world located 300 light years from Earth is the most similar to our planet in estimated size and temperature.
“This intriguing and distant world gives us even greater hope that a second Earth is among the stars, waiting to be discovered,” said Thomas Zurbuchen, associate administrator of the direction of NASA’s scientific missions in Washington.
According to him, the data collected by missions like Kepler will continue to produce “astonishing discoveries”.
This new planet is only 1.06 times larger than Earth. The amount of stellar light it receives from its host star is equal to 75% of that which Earth receives from our Sun. This means that the temperature of the exoplanet can also be similar to that of our planet, say the researchers.
However, unlike Earth, this planet orbits a red dwarf. Although none have been observed in this system, this type of star is known for its stellar surges which can make the environment of a planet difficult for all potential life.
