What is Lagrange Point?
1.
A Lagrange point is a place relative to two large bodies (e.g, the Sun and the Earth, or the Sun and Jupiter) where the gravitational and centrifigal forces on a small body that remains at the same point relative to the two large bodies are balanced.
x - (1 - ì)(x - ì)/|x - ì|³ - ì(x + 1 - ì)/|x + 1 - ì|³ = 0
