On Wednesday (Feb. 1) a comet that has not visited the Earth since the last Ice Age and the time of the Neanderthals will make its closest approach to our planet, or perigee. 

Excitingly, the comet C/2022 E3 (ZTF), which last passed through the inner solar system around 50,000 years ago, will be at its brightest during this time and may even be visible to the naked eye under the right conditions. The comet should be observable for days as it approaches our planet and then recedes on its way to the outer solar system.
