Threatens Earth asteroid has two moons

Scientists have found that threatens Earth asteroid has two moons. Asteroids are often accompanied by one natural satellite, but the phenomenon when a space object of this type has a double escort, is not common.

Asteroid Florence was opened and received the status of “potentially threatened” in 1981. In the first days of September, Florence went to the Ground almost close (by cosmic standards). From the blue planet an asteroid separated by only 7,000,000 kilometers. The diameter of this celestial body reaches five kilometers in the case of direct contact with the planet Earth would cease to exist all life. If you add up the strike force the world’s nuclear weapons, the impact force Florence on the planet’s surface would be many times more.

The asteroid is accompanied by two objects with a diameter of about 100-300 meters. The first wraps around “overlord” for eight hours. The second makes a complete revolution around the asteroid for 22-27 hours. Despite their modest space standards, the size of each of the satellites more massive than the fallen in 2013 the Chelyabinsk meteorite.

His vision of the formation of satellites around asteroids was introduced in 2007 by the American astronomer with Russian roots Nicholas gorkavyy. He suggested that in the gravity field of the asteroids get smaller celestial body they impinge on the surface of the asteroid, and the shock wave throws into space debris. Not being able to overcome the pull of a larger object, they form the ring around it, gradually drawing to itself more of the smaller body and merging with them. According to Garkavogo, on the same principle in its time was formed the Moon.
