US: A comet that last appeared in the night sky when Neanderthals still roamed the Earth is set to make a reappearance early next year.
The C/2022 E3 (ZTF) comet orbits the sun every 50,000 years and will pass within 26 million miles of Earth on 1 February 2023, making it visible to the naked eye. It is already visible using binoculars and low-level telescopes when the skies are clear, and should become visible without specialist equipment by mid to late January.
Astronomers have already been tracking the E3 comet, revealing a blue-green coma and a golden tail.
E3 will be the first comet to light up the sky since the Neowise comet in summer 2020.
First discovered by the Zwicky Transient Facility (ZTF) in California, the E3 comet has since been photographed by astronomers at NASA.
The E3 comet got its name for being the third comet discovered in the fifth fortnight of the year.
Astronomers advise anyone hoping to see the E3 comet to pick a dark place free of ambient light and allow 30 minutes for eyes to adjust.
“Comets are intrinsically highly unpredictable objects, since their brightness depends on the scattering of sunlight from dust particles in the comet’s coma and tail,” comet-tracking website In-The-Sky noted.
