NASA's Lucy spacecraft discovered a second asteroid during its flyby of Dinkinesh, revealing it as a binary pair.
The data gathered will be used to prepare for the next close-up look at an asteroid, the main belt asteroid Donaldjohanson, in 2025.
The larger body measures approximately 0.5 miles at its widest, and the smaller one is about 0.15 miles in size.
NASA's Lucy spacecraft, during its flyby of the asteroid Dinkinesh, discovered a second asteroid, effectively revealing Dinkinesh as a binary pair. The larger body measures approximately 0.5 miles at its widest, and the smaller one is about 0.15 miles in size. The encounter served as an in-flight test of the spacecraft, specifically focusing on testing the system that allows Lucy to autonomously track an asteroid as it flies past at 10,000 mph. The data gathered will be used to prepare for the next close-up look at an asteroid, the main belt asteroid Donaldjohanson, in 2025.
The discovery was made during a flyby of Dinkinesh in the main asteroid belt near Mars. The Lucy spacecraft was launched on October 16, 2021, and is on a 12-year mission to explore the Trojan asteroids near Jupiter. The data collected during the flyby will offer insight into small asteroids and help prepare for future asteroid flybys. The asteroid is located 300 million miles away in the main asteroid belt beyond Mars.
