Results of the year 2016: the major discoveries in the field of space
2016 was a year of several important discoveries in the field of space. Scientists were able to "catch" gravitational waves, whose existence is predicted by Albert Einstein, open the "second Earth" at the nearest star to the Sun, and to learn about the existence of the nine planets. January 20 astronomers Michael Brown and Konstantin Batygin the University of California in Pasadena announced that they have discovered beyond the orbit of Pluto Neptune-sized object whose mass exceeds the mass of the Earth 10 times. The nearest point of the ninth planet approaches the Sun at a distance of seven times the radius of Neptune's orbit - 200 astronomical units (an astronomical unit is the distance from the Sun to the Earth). The far point of the orbit away from our star at 600-1200 astronomical units.
