James Webb’s Halo Orbit

The James Webb Space Telescope will not orbit the Earth like Hubble but will in fact orbit the Sun. It will travel for approximately 30 days before reaching what is known as the second Lagrange point, or L2, 1 million miles away. The orbit around this specific point in space will ensure that the telescope remains in the same relative position to the sun and the earth, so that the telescope remains unaffected by the heat and light.
