A pesar de su tamaño, el asteroide de 120 metros, científicamente llamado 2024 JZ, no representa una amenaza para el planeta, pues pasará a una distancia de 4,2 millones de kilómetros, sin embargo, aunque puede parecer lejano, NASA todavía clasifica al asteroide como un “objeto cercano a la Tierra”.

Estos Objetos Cercanos a la Tierra (OCT) suelen ser cometas y asteroide influenciados por la atracción gravitacional de planetas cercanos, alterando sus órbitas y acercándolos a la Tierra.

Estos cuerpos, mayormente compuestos de hielo de agua con partículas de polvo incrustadas, tienen orígenes distintos: los cometas se formaron en el sistema planetario exterior, donde prevalece el frío, mientras que la mayoría de los asteroides rocosos surgieron en el sistema solar interior, entre las órbitas de Marte y Júpiter.

Esta noche, se espera una colisión más cercana cuando el asteroide 2024 JT3 pase a solo 19 mil 300 km de la Tierra.

En tanto, Juan Luis Cano, de la Oficina de Defensa Planetaria de la Agencia Espacial Europea (ESA), asegura que la Tierra está “absolutamente” segura, sin ninguna posibilidad de colisión. Cano explica que los objetos de 5 a 10 metros se desintegrarían en la atmósfera, liberando pequeños meteoritos al suelo.

A diferencia de los meteoros, los OCT son lo suficientemente grandes como para atravesar la atmósfera sin desintegrarse. Sin embargo, estos eventos son rutinarios y representan una amenaza mínima para la Tierra.
