China’s Tsuchinshan Observatory discovered Comet C/2023 A3 (Tsuchinan-Atlas) in January 2023. It will reach its perihelion on September 27 and its closest point to Earth on October 12, potentially becoming the brightest comet of the year. The comet may be visible to the naked eye, with a predicted magnitude of 1.9 to 3.4. Magnitude measures brightness, with lower numbers indicating brighter objects.
