unstable Lagrangian point
subject			fact

unstable Lagrangian point	has equilibrium unstable
	is a kind of Lagrangian point
Lagrangian point	has location a point in the orbital plane of the system
rotating coordinate	has frame of reference rotating reference frame
coordinate	has component coordinate component
point	has dimensions 0

Kinds of unstable Lagrangian point :

• inner Lagrangian point (4 facts) (L1) - An unstable Lagrangian point between the two bodies on the line passing through the centers of mass of the two bodies. Mass transfer occurs through this point in a close binary star system.
• L2 (3 facts) - An unstable Lagrangian point beyond the most massive body on the line passing through the centers of mass of the two bodies.
• L3 (3 facts) - An unstable Lagrangian point beyond the less massive body on the line passing through the centers of mass of the two bodies.
