Comet likely last seen when Neanderthals walked Earth could soon dazzle in the night sky

Quote

A recently discovered comet, known as C/2023 A3 Tsuchinshan–ATLAS, will make its closest approach of Earth on Saturday. Sky-gazers won’t want to miss the event since it may be the last time the comet will be seen in the night sky for another 80,000 years.

On Saturday, the comet will come within about 44 million miles (nearly 71 million kilometers) of Earth. The comet is making its first documented flyby of our planet, according to NASA. With its 80,000-year orbit, the celestial body would have been last seen from Earth at the time of the Neanderthals.

Those looking to catch a glimpse of the once-in-a-lifetime event will want to look in the western part of the night sky, shortly after sunset, according to EarthSky.
