The official name of the found cosmic body is Kepler-452b. The fact is that there is a planet in the "habitable zone", so far only conditions and some properties of Kepler-452b are known.
The size of the planet is much larger than ours - by about 60%. The year there lasts a little longer than we have - about 385 days. The planet has its own heating star next to it, very similar to our Sun. The only difference is that the distance from Kepler-452b to this star is slightly more than from us to the Sun. But the difference is insignificant - of the order of several percent.
Scientists believe that the age of the "second Earth" is more than 6 billion years. And the nearby star is much older than the Sun - about 1.5 billion years. It is possible that there is water on the surface, since the temperature conditions for this are quite suitable. The distance from us to possible brothers is enormous - more than 1,400 light years.
