Scientists Predict Rare Naked-Eye Comet May Disintegrate Before Reaching Closest Point To Sun

News 18  

Scientists have warned that a rare naked-eye comet may disintegrate before it reaches its closest point to the Sun, according to a recent study. Comet Tsuchinshan-ATLAS was discovered in January 2023 by China’s Purple Mountain Observatory and later identified by the Asteroid Terrestrial-impact Last Alert System in South Africa. However, a recent study led by Czech-American astronomer Zdeněk Sekanina suggests that the comet may not reach its expected brightness. Sekanina’s research points to several signs of impending collapse, including the comet’s failure to brighten as much as similar comets from the Oort Cloud and the appearance of a fragmented nucleus and unusually narrow tail.
