(614689) 2020 XL5

(614689) 2020 XL5 is a Mars trojan asteroid, orbiting the Sun in a 1:1 resonance with Mars. This means it shares Mars' orbit but occupies a stable Lagrangian point, specifically the L4 Lagrangian point, which is located 60 degrees ahead of Mars in its orbit. It was discovered on December 12, 2020, by the Pan-STARRS 1 telescope at Haleakala Observatory, Hawaii.

The designation (614689) indicates that it is the 614689th minor planet to be given a permanent number by the Minor Planet Center. The "2020 XL5" part of the name refers to the year of discovery (2020) and the discovery designation, where "XL" indicates that it was discovered in the second half of December and "5" signifies that it was the fifth object discovered during that period.

(614689) 2020 XL5 is a relatively large Mars trojan, with estimates suggesting a diameter of around 1.2 kilometers. This makes it larger than the other known Mars trojan, (5261) Eureka, and one of the largest known Mars trojans discovered to date. Its size and orbital characteristics have made it a subject of interest for astronomical studies, particularly those aimed at understanding the formation and evolution of the Solar System and the dynamics of stable orbital configurations. Studies of its composition and orbital parameters provide insights into the population and characteristics of Mars trojans and their potential origins.
