Researchers studying the lone surviving binary asteroid in the Trojan belt orbiting Jupiter have revealed that the chaos at the beginning of our solar system may have been shorter but more violent than previously thought. A new study on the binary asteroid Patroclus-Menoetius reveals that within the first 100 million years of the solar system's existence, Jupiter and Saturn shoved Uranus and Neptune away from the sun towards the Kuiper belt, a mass of primordial celestial bodies, in a kind of cosmic eviction. The binary asteroid consists of a pair of celestial bodies both roughly 100km (62 miles) in diameter that are found within the Jupiter Trojan belt, a mass of objects that orbits the sun in line with the gas giant of our solar system. "The Trojans were likely captured during a dramatic period of dynamic instability when a skirmish between the solar system's giant planets - Jupiter, Saturn, Uranus and Neptune - occurred," David Nesvorny, one of the team from the Southwest Research
