Sun-Earth L1 Point

Lagrange points are locations in space where the gravitational forces of two large bodies balance each other, making them useful for satellites due to minimal orbit corrections required. There are five Lagrange points for any combination of two orbital bodies, with L1 to L5 located in the orbital plane of the two large bodies. The L4 and L5 points are stable for certain mass ratios, and have been used by planets to hold trojan asteroids, while humans have utilized L1 and L2 for space exploration, particularly for the Deep Space Climate Observatory and the James Webb Space Telescope.learn more on wikipedia
