Word History and Origins
Origin of Selam1
Example Sentences
A satellite asteroid, which the team named "Selam," was orbiting Dinky.
As Lucy sent more data back to Earth, the researchers discovered something surprising: Selam was not just one moon, it was a contact binary -- or two moons melded together.
The researchers noted that the unusual arrangement challenges existing theories about how asteroids and other celestial bodies formed over time and provides additional insight into the internal structure, dynamics and evolutionary history of both Dinky and Selam.
"With the additional observations taken by the spacecraft, we were able to better analyze features such as Dinkinesh's rotation speed and Selam's orbit pattern. We also have a better understanding of what materials they're possibly made of, bringing us a step closer to learning just how terrestrial bodies are created."
Some of the debris could have aggregated to form Selam, while another portion of the fragments rained back down on Dinky as boulders and created the ridges photographed by the Lucy spacecraft.
