Comet C/2023 A3 Visible This Week

Comet C/2023 A3, also known as Tsuchinshan-ATLAS, is nearing its closest approach to the Sun on September 27 and has become unexpectedly bright, making it potentially visible to the naked eye. This comet, which last passed near Earth approximately 80,000 years ago, is currently observable in the early morning sky and is expected to be most visible just before dawn from September 27 to October 2. Astronomers anticipate that as it nears the Sun, its brightness may rival that of the brightest stars, with its visibility shifting to the evening sky after October 12. NASA astronaut Matthew Dominick shared a timelapse video of the comet from the International Space Station, describing it as a fuzzy star-like object. While visibility may vary, enthusiasts are encouraged to use binoculars for a better view. Comet A3 represents a unique opportunity for skywatchers, as it is expected to return in another 80,000 years.
