Skywatchers will have a rare opportunity to witness a spectacular event later this week as a comet named Tsuchinshan-ATLAS passes by Earth before disappearing into the vastness of space. First detected in January 2023 by astronomers at the Tsuchinshan Observatory in China, this comet has been visible for close to two years. It was later observed in South Africa using the ATLAS telescope. Comets are icy objects that orbit the Sun and leave behind long tails, remnants from the solar system's formation billions of years ago. The Tsuchinshan-ATLAS comet, originating from the Oort Cloud on the outer edge of the solar system, may orbit the Sun once every 80,000 years. There is a chance that it may never return due to gravitational interactions with other objects as it moves away from the Sun.
This comet's closest approach to Earth will occur on October 12, at a distance of 44 million miles. It will shine brightest on October 9, when dusty debris scatters sunlight towards Earth, a phenomenon known as forward scattering. Observers may be able to see the comet during the day if it is bright enough."Nichols expressed that viewing the comet Neowise is a rare opportunity worth seizing, as such occurrences are infrequent. The comet will be visible to the naked eye starting from October 9 and throughout the remainder of the month. For a breathtaking sight, experts recommend observing from the darkest location possible with a view of the western horizon. Post-sunset viewing is possible, albeit the faint appearance of the comet low in the sky where it has descended. To enhance the viewing experience, consider using a telescope or binoculars. Although the comet may diminish in brightness after October 9, it will remain observable. Take advantage of this unique opportunity, as such celestial displays may not present themselves again in a lifetime."
