Rare Comet Tsuchinshan-ATLAS Visible Tonight for First Time in 80,000 Years

The comet, originating from the distant Oort Cloud, is best viewed post-sunset in the western sky.

  • Comet Tsuchinshan-ATLAS, also known as C/2023 A3, is visible in the night sky and won't return for another 80,000 years.
  • The comet reached its closest point to Earth on October 12, 2024, at a distance of approximately 44 million miles.
  • Best viewing conditions are 45 minutes after sunset in the western sky, with the comet positioned 30 degrees from the sun.
  • Despite the bright gibbous moon, the comet remains visible, aided by its position near the bright star Arcturus and planet Venus.
  • Discovered in 2023, Tsuchinshan-ATLAS is a long-period comet from the Oort Cloud, a theoretical region of icy bodies surrounding the solar system.
