The primary asteroid to be visited by NASA’s space rock-hopping craft Lucy has lastly been given a reputation. The tiny asteroid in the primary asteroid belt situated between Mars and Jupiter has obtained the moniker “Dinkinesh” or ድንቅነሽ in Amharic, the language of Ethiopia, which implies “you’re marvelous.”
Dinkinesh was found in 1999, however like tens of millions of different main-belt asteroids, it did not get a reputation, solely receiving a designation quantity when its orbit was effectively decided. First recognized beneath its provisional designation as 1999 VD57, the asteroid later entered catalogs as 152830. A correct title was solely proposed when the rock was chosen as a goal for NASA’s Lucy mission.
Evolution lovers might acknowledge the title Dinkinesh as it’s the different title of the fossilized Australopithecus afarensis skeleton referred to as “Lucy”, which was found in 1974 in Ethiopia.

“This mission was named for Lucy as a result of simply as that fossil revolutionized our understanding of human evolution, we count on this mission to revolutionize our understanding of the origin and evolution of our solar system,” Lucy challenge scientist at NASA’s Goddard Area Flight Middle Keith Noll, mentioned in a statement (opens in new tab). “We’re excited to have one other alternative to honor that connection.”
Dinkinesh will likely be first up in a packed tour for the Lucy spacecraft when it reaches the tiny asteroid on Nov. 1, 2023. The space rock wasn’t initially a part of the 12-year tour that can see the spacecraft go to 9 different asteroids and was solely added in January.
Dinkinesh was added to Lucy’s itinerary as a result of the spacecraft’s operators suppose that the tiny asteroid can be utilized to check the probe’s progressive terminal monitoring system. The system will enable Lucy to exactly picture the asteroids it encounters because it passes by them at excessive speeds.
The truth that Dinkinesh is beneath half a mile (beneath a kilometer) in diameter means it’ll present a wonderful check of Lucy’s high-speed imaging capabilities earlier than the spacecraft begins its major science mission of investigating the never-before-explored Jupiter Trojan asteroids.
This huge group of asteroids shares the orbit of Jupiter, the solar system‘s largest planet. Astronomers consider that these Trojan asteroids are fossilized remnants of the fabric that fashioned the planets of the solar system over 4.5 billion years in the past.
“That is actually a tiny little asteroid,” Hal Levison, a planetary scientist at Southwest Analysis Institute (SwRI) and Lucy’s principal investigator, mentioned about Dinkinesh within the assertion. “A number of the staff affectionately seek advice from it as ‘Dinky.’ However, for a small asteroid, we count on it to be a giant assist for the Lucy mission.”
The go to to Dinkinesh will not be only a check of Lucy’s instrumentation. Researchers are additionally enthusiastic about what they’ll be taught from the asteroid itself, which would be the smallest major asteroid belt object ever explored by a space probe.
When it comes to dimension, Dinkinesh is definitely extra like a near-Earth asteroid than a main-belt object, as these are typically larger. Astronomers hope that the rock might assist them uncover how asteroids change as they go away their place between Jupiter and Mars and head nearer to our planet.
“At closest method, if all goes easily, we count on Dinkinesh to be 100s of pixels throughout as seen from Lucy’s sharpest imager,” Simone Marchi, a senior analysis scientist at SwRI, mentioned within the assertion. “Whereas we can’t be capable to see all the small print of the floor, even the overall form might point out whether or not near-Earth asteroids — which originate in the primary belt — change considerably as soon as they enter near-Earth space.”
Meaning, simply because the Lucy skeleton proved revolutionary to our understanding of human evolution, Dinkinesh might be viral in our understanding of the evolution of the solar system.
