CNN —Dinkinesh, a small asteroid that NASA’s Lucy mission visited last week, continues to surprise. At first, images suggested that the space rock was part of a binary pair, with a smaller asteroid orbiting Dinkinesh. The first image taken by the spacecraft during its closest approach revealed the companion, but not the fact that it was a contact binary. “Contact binaries seem to be fairly common in the solar system,” said John Spencer, Lucy deputy project scientist at the Southwest Research Institute, in a statement. The skeleton has helped researchers piece together aspects of human evolution, and NASA Lucy team members hope their mission will achieve a similar feat regarding the history of our solar system.
