Um asteroide atingindo a Lua parece inofensivo. Mas cientistas alertam: isso poderia causar caos ao redor da Terra. Satélites essenciais ficariam ameaçados

Pesquisadores calcularam que um asteroide de apenas 60 metros já seria capaz de lançar enormes fragmentos lunares no espaço. Sem atmosfera, nada impediria os detritos.

Essas rochas viajariam em alta velocidade entre a Terra e a Lua. Parte delas poderia atingir satélites usados em GPS, internet, TV e previsão do tempo.

O estudo mostra que o impacto criaria uma verdadeira nuvem espacial. Pequenos fragmentos poderiam permanecer em órbita durante anos, aumentando o risco de colisões.

Os cientistas também alertam para a Síndrome de Kessler. Um efeito em cadeia onde colisões geram ainda mais lixo espacial, tornando algumas órbitas inutilizáveis.

Hoje, telescópios monitoram milhares de asteroides próximos da Terra. Missões como a DART já mostraram que desviar objetos espaciais pode ser possível no futuro.
