Confira 5 curiosidades sobre os cometas

Os cometas são um corpo celeste composto por gelo, poeira e gases, que desenvolve uma cauda quando se aproxima do Sol. Geralmente originam-se nas regiões mais distantes do Sistema Solar. Confira nos próximos stories 5 curiosidades sobre os cometas.

Os cometas foram formados há aproximadamente 4,5 bilhões de anos, por matéria nebulosa - a mesma que deu origem aos planetas, lua e asteroides.

Os cometas possuem três partes principais: o núcleo, a cabeleira e a cauda - e são formados principalmente de rocha, poeira e gelo.

Um dos cometas mais famosos é o Halley. Ele entra no Sistema Solar a cada 76 anos. Estima-se que ele volte a aparecer em julho de 2061.

Ao viajar em direção ao Sistema Solar, os cometas podem desenvolver três tipos de órbita: Parabólica, Hiperbólica e Elíptica.
