Researchers at Cornell University have developed a new method for estimating the age of asteroids using dynamics, demonstrating this approach on the asteroid Selam, found to be around 2-3 million years old.
An asteroid discovered last November is in fact a solar system toddler – just 2-3 million years old, a Cornell University-led research team estimates using novel statistical calculations.
The team derived the age of Selam, a “moonlet” circling the small asteroid Dinkinesh in the main asteroid belt between DOI: 10.1051/0004-6361/202449716
