Asteroid that hit Botswana in 2018 likely came from Vesta
On June 2, 2018, a small asteroid was discovered on an impact trajectory with Earth. Eight hours later, a video camera in South Africa recorded a bright fireball over Botswana. An international team of researchers have now published their findings in the journal Meteoritics and Planetary Science after they tracked down the surviving meteorites deep inside the Central Kalahari Game Reserve in central Botswana.
“Combining the observations of the small asteroid in space with information gleaned from the meteorites shows it likely came from Vesta, second largest asteroid in our Solar System and target of NASA’s DAWN mission”, said lead author and meteor astronomer Peter Jenniskens of the SETI Institute and NASA Ames Research Center. ....
