The comet C/2023 A3 Tsuchinshan-ATLAS is currently making its closest approach to Earth, reaching a distance of approximately 43,911,824 miles on October 13, 2024. This comet, which has an orbital period of 80,000 years, is expected to be visible to the naked eye in the western sky just after sunset until October 26, weather permitting.
Discovered in 2023 by the Tsuchinshan Observatory in China, in collaboration with the ATLAS system, C/2023 A3 is believed to originate from the Oort Cloud. As it nears the Sun, the comet releases materials forming a bright head and long tails of dust and gas, creating a striking visual display.
Bill Cooke, head of NASA's Meteoroid Environment Office, noted that bright comets are rare, making this event particularly significant for astronomy enthusiasts. The comet's tail, composed of ice and dust, is estimated to extend up to 18 million miles.
Observers are encouraged to use binoculars for an enhanced viewing experience, especially as the comet ascends higher in the sky each evening. Optimal viewing times are expected around 8:00 PM. With its brightness comparable to Venus, the comet will gradually diminish in visibility after its closest approach.
For optimal observation, the public is advised to focus on the western horizon during sunset. The Society of Astronomy of the Caribbean has reported successful sightings and is organizing public viewing events in various locations.
