NASA’s Lucy finds a wobbling peanut-shaped asteroid with signs of ancient water
NASA's Lucy spacecraft has provided new insights into the asteroid Donaldjohanson, revealing it to be a peanut-shaped object with a complex rotation and evidence of past water exposure. These findings help scientists understand the evolutionary history of asteroids in the main belt.
Why it matters
Studying asteroid composition and history provides critical data for planetary science and future space exploration missions.
Even relatively small asteroids can have surprisingly eventful histories. NASA's Lucy spacecraft recently revealed that asteroid Donaldjohanson is a wobbling, peanut-shaped object that has been shaped by collisions, sunlight, and even a brief encounter with liquid water long ago.
