WebThe L2 point has been chosen by NASA as the future site of a large infra-red observatory, the "Next Generation Space Telescope", renamed in honor of a late NASA director The James Webb Observatory. There exist altogether 5 Lagrangian points in the Sun-Earth system and such points also exist in the Earth-Moon system. WebThe L2 point of the Earth-Sun system was the home to the WMAP spacecraft, current home of Planck, and future home of the James Webb Space Telescope.

Five Lagrange points form between any two bodies in the space (say Sun and Earth). According to my understanding, Lagrange points L1, L4 and L5 can form because gravitation pull can cancel out here as these are between Sun and Earth (where gravitational pull is in two different directions).

At this point, with the Earth, moon and sun behind it, a spacecraft can get a clear view of deep space. WebL2 is further away than the Moon, almost 4 times further, I believe. The shadow of the Earth is teensy at that point, that's not why it's there. It's there because it's stable and it's able to point away from Earth, Moon, and Sun all at the same time and thus avoid our combined infrared interference. chloe ting slim armsWebFor example: imagine the Earth going around the Sun in a circular orbit. Then there are five Lagrange points where we can put a satellite. Three of them lie on a line through the Sun and the Earth.
