A comet that takes 80,000 years to orbit the sun is approaching its most visible appearance for sky watchers across the country, including in California.
Initially classified as an asteroid, the comet, named C/2023 A3 Tsuchinshan-ATLAS, is being dubbed the “comet of the century” due to its potential brightness.
According to NASA, this comet will be at its nearest point to Earth over the upcoming weekend. It is believed to have originated from the Oort Cloud, a vast region of icy debris surrounding our solar system, located far past Pluto.
When can you see the comet?
The comet’s most spectacular view in the evening sky is expected during a two-week period from October 12 to October 26. As the comet rises higher in the sky, it may become more challenging to see with the naked eye and might begin to fade either on Halloween or the week prior, depending on its brightness.
Following this period, viewing will require a telescope, as it will be dimmer, and the brightness of the moon could also interfere with visibility.
How to observe comet C/2023 A3 Tsuchinshan-ATLAS
For optimal viewing, plan to gaze at the sky after sunset. On Saturday, the comet will be visible close to the horizon approximately 45 minutes after sunset and will set about 90 minutes later. It’s advisable to find a location away from city lights, and using binoculars can enhance the experience.
