A comet last seen by the Neanderthals is approaching Earth and could be seen by the naked eye sometime at the end of January and the beginning of February 2023.
The green comet, dubbed “C/2022 E3 (ZTF)” was discovered by astronomers in February 2022. It is currently too dim to be seen without a telescope.
The comet is estimated to complete an orbit of the Sun once every 50,000 years, meaning the last time we saw the comet was in the Upper Paleolithic period when humans began to expand throughout Asia and Europe.
