NASA’s Lucy Reveals Wobbling, Peanut-Shaped Asteroid

Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history.

NASA’s Lucy Spacecraft Takes Its 1st Images of Asteroid Donaldjohanson

NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid.

Data From NASA’s WISE Used to Preview Lucy Mission’s Asteroid Dinkinesh

Researchers have utilized infrared survey data to refine the asteroid’s size and surface brightness in support of the Nov. 1 encounter by NASA’s Lucy mission. NASA’s Lucy mission will soon have its first asteroid encounter as the spacecraft travels through deep space en route to Jupiter’s orbit. But before the spacecraft passes 265 miles (425 […]
