On June 2, 2018, astronomers detected a small asteroid merely eight hours before it struck the Earth’s atmosphere.
It was detected using the 60-inch telescope at Mt. Lemmon, which is part of the Catalina Sky Survey in Arizona
When the asteroid designated 2018 LA made impact, it produced a terrific explosion when it disintegrated 30 miles above Africa.
A team of researchers are now finding some of its meteorite fragments on the Central Kalahari Game Reserve in Botswana. The rocks will be studied further by a scientist in a research consortium.
This is the third time that an asteroid had been detected before impact and the second time fragments were recovered.
