In this period when we talk about Covid-19, here is a completely unexpected news: we have escaped, for some lands of our planet, a catastrophe.
A Asteroid 20 meters in diameter touched the Earth’s atmosphere, passing about 20,000 km away. Its tentative name is Asteroid (NEO) 2020 HF5.
This Asteroid had gone completely unnoticed, so we learn from the news that just appeared on Facebook (and gradually from other sources), on the page “ASTROFILI MONTELUPO GROUP”, where the director Maura Tombelli managed to take the orbital measures.

The information on the sites dedicated web they speak of a minimum distance that was expected to be 245,138 km, i.e. a disproportionate waste, only now known to have escaped danger (this is available, except for errors).
There news will require additional data and measurements from Centro Mondiali, which instead show us how April 29th day when a other Asteroid, but at a much greater distance than the one passed yesterday evening April 24th.
Coronavirus: devastating impact also on the WEATHER

NASA has asked for more funds for a few years for research aimed at intercepting Asteroids that in the future could impact the Earth’s atmosphere, generating an explosion equal to that of some atomic bombs. Not only that, cooperation is requested from all the World Research Institutes, funding from governments, as the risk of an impact exists, and a meteorite even smaller than 20 meters in size could cause damage.
Events such as yesterday could cause damage if they occur near a metropolitan area. The morning of February 15, 2013, in the region south of the Urals, Russia, a meteorite exploded into the atmosphere in an area not densely populated, but its explosion caused a shock wave that shattered the glass of hundreds of buildings, and many were injured.
The June 30, 1908, a possible impact or explosion, this aspect has not been determined, of a large meteoroid or a comet, at a height between 5 and 10 km from the ground it generated a shock wave that devastated an area of about 2,150 square km, cutting, it is estimated, between 60 and 80 million trees.
It is estimated that the shock wave of the explosion could have been assimilated to a Richter scale grade 8 earthquake. An explosion of this magnitude is capable of destroying a large metropolitan area.
