Um ano-luz é uma unidade de medida astronômica que representa a distância que a luz percorre em um ano, no vácuo do espaço. Isso equivale a cerca de 9,5 trilhões de quilômetros. Essa medida é essencial para compreender as vastas distâncias no universo, permitindo aos astrônomos estimar distâncias entre estrelas, galáxias e outros objetos celestes. O ano-luz não se refere a uma duração de tempo, mas sim a uma distância, e sua compreensão é fundamental para explorar e estudar o cosmos. . . #ASTRO
