An asteroid-sized refrigerator was spotted by telescopes in Hawaii on Saturday just before it collided with the Earth's atmosphere and burned like a fireball in the sky south of Puerto Rico. Innocent space rock, officially called the 201
9 MO, never had a chance to get to the ground or do a lot of damage, as only about a tenth of the size of the car that
exploded in the atmosphere over Russia in 2013 .
You can see a fireball in images from NOAA / NASA satellites below:
According to data from NASA bombs and cars, our atmosphere is affected by a meteor size of this magnitude or greater approximately once a year. What is most interesting for the MoD in 2019 is the fact that it was previously spotted by telescopes. This happens only four times in history, according to Italian astronomer amateurs Ernesto Guido.
The other three times happened in the last 12 years, including
asteroid 2018 LA, who did everything to the ground in Africa.
This does not mean that the cosmic rocks are becoming more aggressive in the 21st century, but astronomical equipment and techniques are improving upon the discovery of incoming asteroids.
According to the International Center for the Planet of the International Astronomical Union , 2019 MO affects the atmosphere around 5:30 pm EDT Saturday.
Peter Brown of West University in Ontario noted that the impact was recorded at an equivalent explosive power of 5,000 tons of TNT.
Of course, the day's notice given in the 2019 case would not be too useful to prepare if it was a much bigger asteroid that flies in the sky. Luckily
NASA and other agencies have set goals to work to track as many of the biggest rocks as possible.
