Trojan asteroids are a group of space rocks that share an orbit with a larger planet, typically located at stable points known as Lagrange points. These points are found 60 degrees ahead of or behind the planet in its orbit. The most well-known examples are the Trojan asteroids of Jupiter, which are located in two clusters around these Lagrange points. Trojan asteroids are thought to be remnants from the early solar system, providing valuable insights into its formation and evolution. They can vary in size and composition, and studying them helps scientists understand the conditions that existed when the planets formed.
