As chances de um meteoro atingir a Terra aumentaram

Astrônomos monitoram o asteroide 2024 YR4, que pode atingir a Terra em 22 de dezembro de 2032.

As chances de impacto subiram de 1,3% para 2,3% em poucos dias.

Isso é normal para asteroides recém-descobertos, e os cientistas esperam que caiam para zero.

A NASA e a ESA monitoram o asteroide usando softwares avançados. Novas observações ajudam a prever sua órbita com mais precisão e reduzir a incerteza.

As chances de impacto podem aumentar temporariamente, pois a Terra continua dentro da incerteza da trajetória.

Até abril de 2024, telescópios poderão estudar o 2024 YR4. Depois, ele ficará invisível até 2028, mas os astrônomos esperam já ter descartado qualquer impacto.

Se o asteroide atingisse a Terra, liberaria uma energia comparável a uma bomba nuclear. Possíveis áreas de impacto incluem oceanos e partes da América do Sul, África e Ásia.

Apesar do baixo risco, cientistas seguem monitorando o 2024 YR4.

Se necessário, será hora de ativar planos de defesa planetária contra asteroides perigosos.
