Instead of orbiting Earth, #NASAWebb will be orbiting the Sun in line with the Earth, around a position in space nearly one million miles from us called Lagrange point 2 (L2): https://go.nasa.gov/2RAnkZw
Here's what that orbit looks like

For L1 (between Earth and Sun), Earth’s gravitational pull counteracts some of the Sun’s pull and thus makes the orbital period of an object at L1, the same as the Earth’s. 2/
Thanks. Twitter will use this to make your timeline better. UndoUndo

For L2 (where we will be), the extra pull of Earth’s gravity decreases the orbital period of an object at L2, making it equal to Earth’s orbital period. The fact that we will be orbiting the L2 point doesn’t change this! 3/3

Understood, but is the orbit around L2 maintained by thrusters or is it something else?
