Discover the key locations where spacecraft can stay in position

  • Lagrange points are gravitationally balanced locations in space
  • They allow objects to stay in position relative to larger bodies
  • There are five Lagrange points between Earth and the sun
  • L1 and L2 are the easiest to reach for space missions
  • L4 and L5 are stable points where Trojan asteroids cluster
  • Lagrange points were first proposed in the 18th century
  • Spacecraft at Lagrange points experience a balance of gravitational and centripetal forces
  • Several spacecraft are currently located at Lagrange points

Lagrange points, also known as Lagrangian points, are gravitationally balanced locations in space where objects can stay in position relative to larger bodies. These points are made possible by the balance of gravitational and centripetal forces between two bodies, such as Earth and the sun or Earth and the moon. There are five Lagrange points between Earth and the sun, with L1 and L2 being the easiest to reach for space missions. L4 and L5 are stable points where Trojan asteroids cluster. The concept of Lagrange points dates back to the 18th century, and spacecraft at these points experience a balance of gravitational and centripetal forces. Currently, several spacecraft are located at Lagrange points, conducting various observations and missions.
