A newly discovered green comet, known as Comet SWAN, has likely shattered as it approached the sun, disappointing many who were hoping for an impressive display in the night sky. This comet, which originated from the Oort Cloud beyond Pluto, had been seen through telescopes and binoculars with its distinctive tail, but experts now believe it is rapidly fading away.
Astrophysicist Karl Battams from the U.S. Naval Research Laboratory stated that we might soon be left with only “a dusty rubble pile” as the remnants of the comet after its close encounter with the sun.
Comets are fascinating celestial bodies made of ice and dust, remnants from the early days of our solar system. Every so often, these ancient travelers make their way through the inner solar system. Jason Ybarra, the director of the West Virginia University Planetarium and Observatory, explained that these comets are like fossils from the formation period of the solar system.
Comet SWAN was first spotted by amateur astronomers who noticed it in images captured by a spacecraft designed to study the sun. Unfortunately, unlike last year when the Tsuchinshan-Atlas comet made a close pass to Earth, Comet SWAN will not come near our planet. Previous comets like Neowise in 2020 and Hale-Bopp and Hyakutake from the 1990s provided stunning views, but SWAN’s visual appeal may not match their spectacular flybys.
The comet, also classified as C/2025 F2, would have been visible shortly after sunset, positioned slightly north of where the sun sets. However, its green hue would have been challenging to detect with the naked eye. Battams noted that this could be the comet’s first trip past the sun, making it more likely to break apart under the intense heat.
After its journey near the sun, any remains of Comet SWAN will drift out into the distant solar system, far beyond its point of origin, leaving experts unsure if it will ever return to our celestial neighborhood. As Battams mentioned, it’s headed so far out that we might never witness its return.
