Trojan asteroids are a large group of asteroids that share Jupiterâ€™s orbit around the Sun. The first of these asteroids was spotted in 1906 by German astronomer Max Wolf. More than 9,800 of these asteroids have been found as of May this year. They are named after a figure of the Trojan War mentioned in Greek Mythology.
NASAâ€™s Lucy mission will be the first in the world to study the Trojan asteroids. Deeper research of these asteroids is critical for the understanding of the planetary origins and the formation of solar system.
