Comet Returns to Earth’s Skies After 80,000 Years

A comet, known as Comet Tsuchinshan-ATLAS or Comet A3, has become visible from Earth for the first time in over 80,000 years. It was first spotted on September 27, coinciding with its perihelion, the closest point to the sun. This long-period comet is expected to exhibit unpredictable behavior, including changes in brightness and tail development as it approaches the sun. Observers can expect to see it as a fuzzy ball with a tail stretching across the sky, potentially visible to the naked eye. The comet will continue to be visible until shortly before sunrise on October 2, 2023. After its initial visibility, there is another opportunity to view the comet in mid-October, provided it survives its close encounter with the sun. Comets often disintegrate during such approaches, making this a critical period for observation. If it remains intact, the best visibility is anticipated from October 12 to October 20, when it will be closest to Earth. During this time, the comet will rise higher in the sky each night, offering a unique chance for stargazers to witness this rare celestial event. The excitement surrounding Comet A3 is heightened by its rarity, as it will not return for another 80,000 years. Starwalk, an astronomical app, has labeled it the "most anticipated comet of the year," drawing attention from both amateur and professional astronomers alike. This event serves as a reminder of the dynamic nature of our solar system and the fleeting opportunities to observe such phenomena.
