A celestial body, discovered on Monday, is an asteroid the size of 2.3 to 5.1 meters. On Wednesday at 17:30 GMT (20:30 MSK), he will fly near the Earth with a relative speed of 9.6 km / s at a distance of 29.1 thousand kilometers.

As a result, the family moved from the asteroid Apollo (to it belong to an object whose orbit lies mostly outside the Earth) in the family of the Aten (asteroids whose orbits are inside the Earth's orbit).
Astronomers say that on average, every few weeks, one meter asteroid invades the Earth's atmosphere and burn it completely, forming a fireball.
