Artist’s idea of a near-earth asteroid.


An asteroid the scale of a fridge was noticed by telescopes in Hawaii on Saturday, simply earlier than it collided with Earth’s environment and burned as a fireball within the sky due south of Puerto Rico. The innocent house rock, formally named 2019 MO, by no means had an opportunity of constructing it to the bottom or doing a lot injury, because it was solely a few tenth the scale of the bolide that exploded within the environment over Russia in 2013

You’ll be able to see the fireball flash in imagery from NOAA/NASA satellites under:

In accordance with fireball and bolide information from NASA, our environment is struck by a meteor this dimension or bigger roughly annually. 

What’s most fascinating about 2019 MO, although, is the truth that it was noticed by telescopes beforehand. That is solely occurred 4 instances in historical past, in keeping with Italian newbie astronomer Ernesto Guido.

The opposite thrice all occurred within the final 12 years, together with asteroid 2018 LA that made all of it the way in which to the bottom in Africa. 

This doesn’t suggest house rocks are getting extra aggressive within the 21st century, however that astronomers’ tools and strategies are getting higher at recognizing incoming asteroids.   

In accordance with the Worldwide Astronomical Union’s Minor Planet Middle, 2019 MO impacted the environment at round 5:30 p.m. EDT Saturday. 

Astronomer Peter Brown from Western College in Ontario famous that the influence was recorded on the equal explosive energy of 5,000 tons of TNT. 

After all, the same-day discover supplied within the case of 2019 MO would not be too useful in making preparations if it have been a a lot larger asteroid smacking into the sky. Luckily NASA and different companies have mandated targets to work towards monitoring as lots of the largest rocks on the market as potential.
