O que aconteceria se o 3I/ATLAS caísse na Terra?

Objetos interestelares que caem na Terra chegariam muito mais rápido que meteoros comuns. Um novo estudo calculou como seriam esses impactos.

As simulações mostram velocidades de impacto próximas de 72 km/s, suficientes para causar danos mesmo em objetos pequenos.

Pesquisadores criaram bilhões de trajetórias virtuais para entender padrões de chegada desses visitantes interestelares.

Três objetos reais já passaram pelo Sistema Solar: ‘Oumuamua, Borisov e 3I/ATLAS, todos com trajetórias hiperbólicas.

As simulações revelam que objetos que atingiriam a Terra tendem a ser mais lentos, desviados pela gravidade do Sol.

Esses visitantes chegariam com maior frequência do ápice solar e do plano galáctico, regiões que concentram o fluxo.

O inverno do Hemisfério Norte teria mais impactos, enquanto a primavera concentraria as colisões mais rápidas.

O estudo não estima quantos impactos ocorreriam, mas mostra onde e quando eles seriam mais prováveis.
