It was only hours from impacting Earth when a boulder-sized asteroid was detected by the NASA-funded Catalina Sky Survey on Saturday morning. NASA said in a press release that the agency estimates the asteroid was about six feet across. (Or, in honor of the Finals, about one foot smaller than the wingspan of LeBron James.) That's small enough that the asteroid would disintegrate in the atmosphere instead of reaching the Earth's surface.
There wasn't much time to pinpoint where the asteroid would land, but a lengthy potential trajectory was put together that stretched from South Africa to New Guinea. It ultimately became a fireball over Botswana, which was on the projected path. The asteroid, moving 10 miles per second before disintegrating miles above the Earth's surface, was seen by many observers and even caught on a webcam, as seen above.
