The object, identified as Centaur 450P/LONEOS, was captured in the process of birth. Researchers observed how a distant centaur can transition into active comet behavior. Scientists are tracking this distant transformation to understand the physical and chemical mechanics that drive icy bodies in the outer solar system to ignite as comets.Why it mattersCentaurs orbit the solar system between Jupiter and Neptune, existing in a transitional state between asteroids
