Astronomers found almost exact copies of the Earth and the Sun
US, WASHINGTON (ORDO NEWS) — Astronomers were able to detect an earth-type exoplanet located on a similar to our orbit, which is located at a distance of 3,000 light-years.
To date, scientists know about a little more than 4000 exoplanets, but at the same time most of them are gas giants that resemble Neptune or Jupiter. Only a few dozen planets resemble ours, belong to the Earth type and have a mass that does not exceed the mass of the Earth more than ten times. And only a few of them are at the right distance from their star in order to maintain a suitable temperature at which liquid water can be present and life develops. All these planets are located next to the red dwarfs.
Stars of this type are considered the most common, but scientists have no idea about whether it is possible to live on them. Of course, red dwarfs can maintain stability over time, which allows life to develop at a low speed. At the same time, they have not so intense radiation, and most of it belongs to the low-energy infrared range.
Some time ago, German astronomers were able to find an exoplanet that resembles the Earth as much as possible. It is located in the yellow dwarf system Kepler-160, the mass of which is almost the same as that of the Sun. A similar indicator is the luminosity of the star.
Previously, specialists knew only about two exoplanets that are too close to the star. But in connection with the discovery of deviations in the motion of these planets, it has been suggested that there are two more planets. One of them is too large, so scientists did not pay much attention to it. The second, KOI-456.04, has a radius that is only 1.9 more than Earth. An interesting fact is that the exoplanet makes a complete revolution around its star in just 378 days. This planet most resembles our world in its characteristics.
