A celestial spectacle is expected to grace the night sky this week as a comet passes by Earth. Comet Tsuchinshan-ATLAS will be bright enough for most people to see with the naked eye throughout October. Here’s how to ensure you don’t miss this rare sight.
What is Comet Tsuchinshan-ATLAS?
NASA describes comets as icy bodies composed of debris leftover from the formation of our solar system. As they approach the sun, they heat up, producing a glowing tail of gas and dust that can extend millions of miles. Comet Tsuchinshan-ATLAS was discovered in 2023 by observers at China’s Tsuchinshan Observatory and an ATLAS telescope in South Africa. The comet was officially named in honor of both observatories.
The comet originates from the Oort Cloud, a region on the outskirts of our solar system filled with frozen debris.
The comet made a close pass by the sun on Sept. 27, an event scientists feared it might not survive. It is now expected to come within 44 million miles of Earth.
