Asteroide 2020 SW passa a 27 mil km da Terra sem risco de colisão

On September 24, 2020, a small asteroid designated 2020 SW passed within 27,000 kilometers of Earth — closer than the satellites that carry our television signals — reminding us that the solar system is not a static backdrop but a living choreography of objects in constant motion. Discovered only days earlier by observers in Arizona, the rock posed no threat, yet its brief proximity was enough to permanently alter its path through space. In the long arithmetic of orbital mechanics, even a near-miss leaves a mark.
