Scientists discover ancient ice giant Chiron shows traits of both asteroids and comets

Scientists have discovered that Chiron, an ancient ice giant in our solar system, exhibits characteristics of both asteroids and comets. Using the James Webb Space Telescope, researchers found that Chiron has a unique surface and atmosphere, containing carbon dioxide, carbon monoxide, and methane. This study, published in Astronomy & Astrophysics, reveals that Chiron's surface holds ice, while its surrounding coma contains gases. This dual nature makes Chiron distinct from other centaur objects and provides insights into the early solar system. Chiron, first identified in 1977, is notable for its comet-like behavior, including gas and dust emissions. It also has a ring system and may have orbiting debris, making it a subject of interest for further study.
