NASA: a planet has been discovered on which water in a liquid state can potentially be

Kepler-186f is 10% larger than the Earth, but its mass and composition are unknown. NASA and the Kepler team reported that they discovered a planet the size of the Earth, which revolves around a dwarf star at a distance that allows for the presence of water in a liquid state.

Now there is a live press conference of scientists. You can ask scholars questions on twitter using the hashtag #AskNASA

Filegiver continues a series of posts about space. The new planet, Kepler-186f, is part of a five-planetary system that rotates around a star called Kepler-186. This star is colder and about 60% smaller than the sun. The detected system is located about 500 light years from Earth in the constellation Cygnus. Kepler-186f is the only planet in its system that is at the required distance from the star in order to have water in a liquid state on the surface. Since liquid water is a key element for the existence of life, scientists call this distance from the star a habitable zone. On planets that are too close to their star, liquid water evaporates. And those who are too far away do not receive enough energy from their star to maintain a climate and atmosphere similar to that on Earth. The planets were discovered using the Kepler apparatus , we wrote about it and its achievements earlier. The device found dozens of exoplanets in the habitable zone, but most of them are gas giants. Kepler-186f is the first, which coincides with the size of the Earth and can potentially have the same atmosphere and water.

Size and composition
Kepler-186f is 10% larger than Earth. Scientists have confirmed the size of Kepler-186f by measuring the dark spot that it forms when flying against the background of its star. Scientists do not yet know the mass and composition of Kepler-186f, but suggest that it may have a rocky surface. Comparison of our solar system with the Kepler-186 star system:
