"Dinky Asteroid's Double Moon Named and Explored by Lucy Mission"

NASA's Lucy spacecraft, on its way to investigate ancient asteroids called the Trojans, discovered that one of its non-Trojan targets, asteroid Dinky, is actually a binary system with its own moon named Selam. To everyone's surprise, Selam itself has a moon, making it the first contact-binary orbiting an asteroid. The Lucy team has now confirmed the name Selam for Dinky's moon, in honor of a fossil nicknamed "Lucy's baby." Further study of Dinky and Selam will help scientists understand how this unique system formed.
