🌍 where
Where is the Lagrange point L2 in the Earth-Sun system used by space telescopes?
Quick Answer
Earth-Sun L2 is about 1.5 million kilometers from Earth on the night side, opposite the Sun. The James Webb Space Telescope operates there in a halo orbit.
The Full Story
The Earth-Sun L2 point is located about 1.5 million kilometers from Earth, on the side opposite the Sun. Space telescopes like the James Webb Space Telescope use this region because Earth and Moon stay mostly behind the spacecraft’s sunshield. L2 is not a perfectly fixed point, so missions orbit around it in a halo or Lissajous orbit. The location offers a cold, stable environment ideal for infrared astronomy.
