NASA’s Lucy spacecraft flew by asteroid Dinkinesh and made a surprising discovery, a close binary! Preliminary statistics show that Dinkinesh is ~0.5 miles (790 m) wide and the binary asteroid is 0.15 miles (220 m) in size. <br /><br />The spacecraft closest approach to the asteroid was about 270 miles (430 km) away and it was flying at 10,000 mph (4.5 km/s).<br /><br />Credit: Space.com | footage courtesy: NASA/Goddard/SwRI/Johns Hopkins APL/NOAO/ASU | edited by Steve Spaleta<br />Music: Alien Invasion by JH Coleman / courtesy of Epidemics Sound
