2010 TK₇

2010 TK7 is an Earth Trojan asteroid, meaning it shares Earth's orbit around the Sun and is located at a gravitationally stable point known as a Lagrangian point (specifically L4). This discovery was significant as it was the first Earth Trojan identified, found in 2010. Trojan asteroids are named after participants in the Trojan War from Homer's Iliad. While Jupiter has a large population of Trojan asteroids, they have also been found associated with Mars, Neptune, and now Earth. These asteroids are thought to have originated from the asteroid belt and were captured into their stable orbits by gravitational forces.12
