      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 ⬇️pic.twitter.com/5kQQrQmdxh

      Question about smaller orbit, what is it revolving around? And how, it's as it has 2 orbits one around Sun which is understandable but how does it achive that second orbit?

      Essentially the gravity from the sun and the earth keep it in that orbit. There are several different Lagrange points at different spots that exhibit similar “balancing” characteristics

      So…. Is it’s clock going to be off due to the fact it’s taking longer to travel around the sun? How many days longer will it take for full rotation?

      One of the special properties of Lagrange points is that they allow for orbital periods around the Sun that are equal to Earth’s even though they have varying distances from the Sun. 1/

      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?

      Yes, thrusters! Read more here under "Rocket Thrusters and Propellant": https://www.jwst.nasa.gov/content/observatory/bus.html …
