The green comet C/2022 E3 ZTF will pass by the Earth after 50,000 years: so you can see it
Comet C/2022 E3 (ZTF), discovered in March of last year, could be seen as a comet. be seen by amateur astronomers in the sky in late January, possibly even with the naked eye.
It was discovered by astronomers using the Zwicky Transient Facility's Wide Field Survey Camera. Since then, the new long-period comet–it completes its orbit around the Sun in about 50,000 years–has increased its brightness considerably and is now close to the Sun. The comet is sweeping across the northern constellation Corona Borealis in the predawn skies, NASA reports.
This December 19 telescopic image (above) shows the comet's bright greenish coma, a It shows a short, broad dust tail and a long, weak ion tail that stretches across a 2.5-degree field of view.
On its journey through In the interior of the Solar System, comet 2022 E3 will be found within the Solar System. It will be at perihelion, its closest point to the Sun, on January 12 and at perigee, its closest point to our planet, on February 1. Comet brightness is notoriously unpredictable, but by then C/2022 E3 (ZTF) could be visible to the naked eye in dark night skies, the space agency reports.
