# How will JWST maintain its elliptical orbit around L2?

I understand that JWST will have a vertical elliptical orbit around L2, but what I don't understand is how the telescope will actually maintain an orbit if there is no body in L2 to actually orbit around. There is no center of mass to pull the telescope inward to maintain a circular orbit around L2 while also orbiting the sun. Does the telescope maintain this orbit using its own power?

• L2 is an equilibrium force point. Unstable, but an equilibrium point. – AtmosphericPrisonEscape Jan 10 at 21:11
