Comet Tsuchinshan-ATLAS, also known as Comet C/2023 A3 and Comet A3, has not been seen from Earth in over 80,000 years. But shortly after sunset on Monday evening, October 14, the rare comet will be visible in the west near the horizon between the star Arcturus and the planet Venus.

Luckily for amateur astronomers, the nights through Saturday are expected to be mostly clear, meaning the chance of catching this once-in-a-lifetime sight is high.

According to CCNY Planetarium, the comet will be visible in some parts of the Northern Hemisphere until October 26, but the further it gets from the sun, the fainter the light will be. However, on Monday, October 14, it will likely be “as bright as the North Star.”
