NASA’s Lucy spacecraft, on its mission to explore the Trojans, recently made a surprising discovery during its encounter with the asteroid Dinkinesh. It turns out that Dinkinesh is actually a binary system, consisting of the asteroid itself and a small natural satellite in orbit around it.
The satellite, which has been named ‘Dinky,’ is a contact binary. This means that the two smaller objects within the satellite are in contact with each other. This finding has taken scientists by surprise, as they did not expect to come across a binary system orbiting an asteroid.
But the surprises didn’t end there. Lucy also spotted a third rock in the asteroid system while capturing the initial images of Dinkinesh and its satellite. Contact binary systems are common in the solar system, but this marks the first time such a system has been observed orbiting an asteroid.
Lucy’s primary objective is to explore the Trojans, a group of asteroids located near Jupiter. These asteroids offer valuable insights into the origins of our solar system and the emergence of life on Earth. The spacecraft is set to visit multiple asteroids over its 12-year mission, with the aim of studying eight Trojan asteroids between 2027 and 2033.
Scientists are thrilled by the unexpected discoveries made by Lucy. These binary systems pose intriguing mysteries that researchers are eager to unravel. By studying these systems, scientists hope to gain a deeper understanding of how asteroids form and evolve, as well as the role they played in the early development of our solar system.
The findings from the Lucy mission have already begun to reshape our understanding of asteroids and their dynamics. With each new discovery, we inch closer to unraveling the mysteries of our celestial neighborhood. Stay tuned as Lucy continues its groundbreaking journey through the cosmos, providing us with unprecedented insights and expanding our knowledge of the universe we call home.
