Looking ahead to the future of the Earth
If the sun develops in the direction of newly discovered relatives, called CoRoT Sol 1, water on the Earth's surface will evaporate, according to a report published in the Astrophysical Journal Letters.
A "sister" to the sun but older than 2 billion years old can herald the future of our central star, and of course the Earth.

'In the next 3 billion years, the sun's radiation may increase, causing the surface of the earth to become too hot and liquid water could no longer exist in the natural state,' said lead researcher Jose Dias. by Nascimento of Rio Grande do Norte University (Brazil).
CoRoT Sol 1 is considered "sister" to the sun in the Milky Way, because they have almost the same mass and composition.
The star is about 6.7 billion years old, 2 billion years older than the sun, and the level of radiation emitted very harshly.
Astronomers used spectroscopy in Hawaii to determine the age of the star, as well as the rotation period of about 29 days, a day less than the sun, according to The Los Angeles Times.
Astronomers say that it is important to study the "sisters" of the sun so that we can see the future of ourselves.
