Another asteroid threatens the earth again! It is called “2024 JR4” and was only discovered at the end of September with a telescope in Chile. A fatal danger? Science editor Christian Mähr has the answer.
First apophis, then Bennu, now the new one! The information about the diameter fluctuates between 50 and 100 meters. It is said that his density is comparable to the Tscheljabinsk-Sasteroid from 2013. It had a density of 3300 kilos per cubic meter, but was only about 20 meters long. This makes 13,000 tons with a spherical shape. He hit the earth in a flat corner with about 19 kilometers per second, which is 23 times faster than a gunball. The thing has apparently already broken down in the air, which is why the pressure wave of the impact can spread down. The asteroid did not hit something special – but there were 1500 injuries due to fragmented window stops.
