No espaço, as distâncias são tão enormes que não usamos quilômetros. Medimos em Unidades Astronômicas (UA), sendo 1 UA a distância da Terra ao Sol, cerca de 150 milhões de km. Para estrelas, usamos o ano-luz, a distância que a luz percorre em um ano: 9,5 trilhões de km. E ainda assim, muitas galáxias estão a milhões ou bilhões de anos-luz, mostrando como o universo é vasto e quase inimaginável. #curiosidades #ciencia #astronomia #espaço #
