flag NASA's discovery of dark comets since 2017 expands understanding of Solar System bodies.

flag NASA's discovery of dark comets, starting in 2017, has expanded our understanding of celestial bodies in the Solar System. flag These objects resemble asteroids but behave like comets, lacking bright tails that make typical comets visible. flag Dark comets are categorized based on size and orbit, and their study could provide insights into early planetary development and the origins of life on Earth. flag The Vera C. Rubin Observatory in Chile is expected to aid in detecting more of these elusive objects, potentially tripling the number known within a decade.
