Idade do planeta Terra?

Se a existência do planeta fosse dividida em um único dia, os humanos teriam surgido apenas nos instantes finais.

A datação radiométrica de rochas é a principal técnica para determinar a idade da Terra.

Esse método envolve a medição de isótopos radiativos e seus produtos de decaimento, permitindo estimativas precisas da idade das rochas.

Analisando a rotação de estrelas em outros sistemas, os cientistas podem deduzir a idade de planetas distantes.

O entendimento dos processos e da cronologia que moldaram outros planetas e estrelas nos fornece informações sobre eventos passados na Terra.

Mas afinal, qual a idade da Terra?

Com uma estimativa de aproximadamente 4,54 bilhões de anos, a Terra se formou cerca de 10 milhões de anos após o nascimento do sistema solar.
