O fenômeno alinhou os planetas Marte, Vênus, Júpiter, Saturno, Urano, Netuno e Mercúrio na perspectiva da Terra. Os que ficaram mais visíveis ao olho nu foram Vênus, Marte e Júpiter.

O fenômeno está relacionado com a velocidade com que os astros giram em torno do Sol. A Terra leva um ano para completar uma volta, enquanto Júpiter leva 12 . Esta configuração é muito rara. Para isso, é preciso que todos os planetas, que possuem velocidades diferentes, consigam se posicionar em suas respectivas órbitas a ponto de estarem na mesma linha.

Quem perdeu a oportunidade de ver o alinhamento de planetas, terá chance de ver fenômenos parecidos, embora menos intensos, ainda este ano. De acordo com o Observatório Nacional, de 12 a 20 de agosto, antes do sol nascer, será possível ver ao mesmo tempo, a olho nu, os planetas Mercúrio, Vênus, Júpiter, Saturno, Urano e Netuno.
