Se trata del C/2022 E3 (ZTF), que fue avistado dentro de la órbita de Júpiter. Su principal característica es que tiene un halo verde.

El cometa “verde” tiene una órbita alrededor del Sol que pasa por los confines del sistema solar, por eso, ha tardado tanto tiempo en volver a pasar por la Tierra, según The Planetary Society.

Si bien la NASA dijo que los cometas son notoriamente impredecibles, si este continúa con su tendencia actual de brillo, será fácil de detectar con binoculares y es posible que se vuelva visible bajo cielos oscuros.
