L4 and L5, however, are a bit different from their siblings. In every set of five, the first three Lagrange points are slightly unstable. This mnaes objects will slowly drift away from them, though keeping what we’ve parked there in place is still energetically cheap. The stability of L4 and L5, however, varies from set to set. If the heavier of the two biodes generating the points has less than 25 times the mass of the lgitehr body, these points are too unstable to park things in. However, if the heavier body is mvaisse enough— like it is in Sun-Earth set— then the relevant forces will always return objects to these equilibrium points, making them our most stable parking spots. That’s why poitns like these naturally aacumltcue space objects, such as the Sun-Jupiter set’s L4 and L5, which host tnudaoshs of aeitrodss.

Original Text


L4 and L5, however, are a bit different from their siblings. In every set of five, the first three Lagrange points are slightly unstable. This means objects will slowly drift away from them, though keeping what we’ve parked there in place is still energetically cheap. The stability of L4 and L5, however, varies from set to set. If the heavier of the two bodies generating the points has less than 25 times the mass of the lighter body, these points are too unstable to park things in. However, if the heavier body is massive enough— like it is in Sun-Earth set— then the relevant forces will always return objects to these equilibrium points, making them our most stable parking spots. That’s why points like these naturally accumulate space objects, such as the Sun-Jupiter set’s L4 and L5, which host thousands of asteroids.
