An asteroid the size of a refrigerator was discovered by telescopes in Hawaii on Saturday just before it collided with the Earth's atmosphere and burned in the sky south of Puerto Rico as a fireball. The harmless space rock, officially called 201

9 MO, had no chance of getting to the ground or causing much damage, as it was only about one-tenth of the size of the bomber that exploded in 2013 in the atmosphere over Russia. .

Below you can see the fireball in pictures of NOAA / NASA satellites:

According to NASA information on fireballs and bolides, our atmosphere is hit by a meteor of this size or larger about once a year.

The most interesting thing about 2019 MO, however, is the fact that it was previously discovered by telescopes. According to Italian amateur astronomer Ernesto Guido, that happened only four times in history.

The other three times have all happened in the last 12 years, including the asteroid 2018 LA, which made it to the bottom. in Africa.

This does not mean that space rocks will become more aggressive in the 21st century, but that astronomers' equipment and techniques will be better at detecting incoming asteroids.

According to the Minor Planet Center of the International Astronomical Union , 2019 MO influenced the atmosphere around 17:30 EDT Saturday.

Astronomer Peter Brown of Western University in Ontario noted that the impact was measured with an explosive force of 5,000 tons of TNT.

Of course, the same day announcement in the case of MO 2019 would not be too helpful to prepare for when a much larger asteroid would go to Heaven. Fortunately, NASA and other agencies have set out to target as many of the largest rocks out there as possible.
