WebMar 27, 2024 · The 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. L2 is ideal for astronomy because a spacecraft … WebOct 18, 2024 · 14. 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). However, I could not understand why L2 …
WebFeb 11, 2024 · The James Webb Space Telescope (JWST) arrived at its new home, Lagrange point L2, on 24 January 2024, after its launch on Christmas Day, 2024. Here, it will stay, orbiting around this gravitationally special position 1.5 million km away for the next 10 or 20 (or more) years, as L2 itself orbits the Sun, keeping Earth behind it.

The extra pull of Earth's gravity decreases the object's orbital period, and at the L 2 point, that orbital period becomes equal to Earth's. Like L 1, L 2 is about 1.5 million kilometers or 0.01 au from Earth (away from the sun). An example of a spacecraft at L 2 is the James Webb Space Telescope, designed to operate … See more In celestial mechanics, the Lagrange points are points of equilibrium for small-mass objects under the influence of two massive orbiting bodies. Mathematically, this involves the solution of the restricted three-body problem See more The five Lagrange points are labelled and defined as follows: L1 point The L1 point lies on … See more Lagrange points are the constant-pattern solutions of the restricted three-body problem.
