Asteroid accelerates in space mysteriously, puzzles scientists

An asteroid named 1998 KY26 is accelerating in a way that gravity alone cannot explain, researchers have found. A new study suggests the 11-metre-wide object is too warm to retain buried ice, challenging the theory that escaping gas is pushing it through space. Japan's Hayabusa2 spacecraft is expected to reach the asteroid in July 2031 for a detailed scientific investigation.
