The video recorded the most powerful collision of a meteorite with the Moon.
On September 11, 2013, a meteorite with a diameter of about 1 meter and a weight of about 400 kg crashed into the lunar surface at a speed of about 61,000 km / h. The flash was so bright (8 seconds, 2.9 ± 0.2 zv. At the peak) that it could be seen from the Earth with the naked eye. Astronomers from the Spanish Observatory at the University of Huelva managed to record this event .
This is the strongest of the collisions of meteorites with the Moon ever recorded on video. After the collision, a crater with a diameter of more than 40 meters remained on the surface of the moon. According to experts, the collision energy corresponds to an explosion of about 15.6 ± 2.5 tons of TNT. ')
The results of the observation of a meteorite collision on September 11, 2013 are published in the latest issue of the Monthly Notices of the Royal Astronomical Society.
It should be noted that stones of this size do not represent a danger to the Earth, because they burn almost completely in the atmosphere. For example, the Chelyabinsk meteorite, which fell on the earth's surface on February 15, 2013, was about 17 meters in size and weighing 10,000 tons by the time it entered the atmosphere.
