A comet that hasn’t been seen in more than 80,000 years is now visible from Earth, captivating astronomy enthusiasts worldwide. Known as Comet Tsuchinshan-ATLAS, or Comet A3, this celestial object is offering a rare viewing opportunity during two distinct periods over the next month.
Comet Tsuchinshan-ATLAS, with an orbital period estimated to exceed 80,000 years, first became visible on September 27, 2023. It is expected to remain visible until just before sunrise on October 2. Observers can expect to see it as a fuzzy ball accompanied by a glowing tail stretching across the night sky.
Minjae Kim, a space expert from the University of Warwick’s astronomy department, explained that “C/2023 A3 has an orbital period of approximately 80,000 years, classifying it as a long-period comet. Its unpredictable behavior allows for potential changes in brightness and tail development as it approaches the sun.”
If the predictions hold true, observers might enjoy an extraordinary sight of the comet with the naked eye, appearing like a fuzzy star with a tail. For those seeking a closer look, using binoculars or a small telescope can reveal intricate details of the comet’s structure and tail.
Notably, September 27 marked perihelion, which is the comet’s closest point to the sun. After this date, Comet Tsuchinshan-ATLAS will begin its journey back to the outer regions of the solar system. According to experts, any viewing opportunity after perihelion is crucial, as comets often exhibit unpredictable behavior and may disintegrate upon nearing the sun.
Another significant viewing chance is anticipated in the middle of October. If Comet Tsuchinshan-ATLAS survives its approach to the sun, it could become increasingly visible to the naked eye from approximately October 12 until October 20. This period is expected to yield the best views, as the comet will be at its closest point to Earth.
This extraordinary event has caught the attention of stargazers and casual observers alike. Starwalk, an astronomical app designed for enthusiasts, has deemed Comet Tsuchinshan-ATLAS the “most anticipated comet of the year.” Its rarity and historical significance add to the excitement surrounding its appearance.
As the days progress, the comet will ascend higher in the night sky each evening until it fades from view for another 80,000 years. This once-in-a-lifetime event serves as a reminder of the wonders that our universe holds and the rare opportunities to observe them.
In summary, the visible return of Comet Tsuchinshan-ATLAS is a significant event that invites people to appreciate the beauty and mystery of our cosmic surroundings. Don’t miss the chance to witness this spectacular celestial phenomenon!
