DALLAS —
Quick Comet Highlights:
- It is called Comet C/2023 A3 Tsuchinshan-ATLAS
- This is the best week to view it
- It won't return for 80,000 years
Comet C/2023 A3 (Tsuchinshan-ATLAS) is making its close approach to Earth, offering North Texas residents a rare opportunity to witness this celestial visitor.
Discovered in 2023 by observers at China’s Purple Mountain Observatory and the ATLAS telescope in South Africa, the comet has traveled from the distant Oort Cloud and will be within 44 million miles of Earth. Oort Cloud is described as a shell that surrounds the solar system and contains icy objects like comets.
Starting around October 14, Comet A3 will be visible low on the western horizon about 45 minutes after sunset. Although it will be quite dim to the naked eye, a pair of binoculars will greatly enhance the view, showcasing its striking tail.
Each evening, the comet will climb a little higher above the horizon, making it easier to spot. However, it will also gradually dim as it moves farther from both Earth and the Sun. By mid-October, the comet will likely be higher in the sky and easier to see without the interference of the Sun's glare. But don’t wait too long! By the end of the month, Comet A3 will have faded considerably, becoming much harder to spot without professional equipment. In fact, this week will be the best chance to catch a glimpse of the comet!
To catch a glimpse of Comet A3, look west after sunset from a location free of obstructing trees or buildings. While binoculars are helpful, smartphone cameras with night modes can also capture faint images. This week provides the best chance for spotting the comet before it fades, and skies are expected to be favorable!
If you miss it, you’ll have to wait a long time—80,000 years to be exact. Happy comet sightings!
