Orbits in Space: Lagrangian points

Orbits in Space: Lagrangian points

Authored and curated by David P. Stern, these pages explore orbits and the "Lagrangian points", where objects will orbit the sun with the same period as the earth. This has applications for solar monitoring spacecraft. The three sections derive the equilibrium properties of Lagrangian points: the calculations only involve algebra and trig, but are rather lengthy. This is a nice introduction to these rather complex theories of orbits in space. Translations to French and (in part) Spanish are also provided.
