The James Webb Space Telescope sits at Sun-Earth L2 — a gravitational balance point 1.5 million kilometres from Earth. It can't be seen with the naked eye, but OrbitalNodes tracks its orbital position in real time using live TLE data from Space-Track.org.
Webb launched on Christmas Day 2021 and reached its L2 orbit in January 2022. At 1.5 million km away it is 4x further than the Moon — completely invisible from Earth but publicly tracked and displayed on OrbitalNodes' live globe alongside the ISS, Hubble, and Crew Dragon.
🔭 VIEW ON LIVE GLOBENo. Webb is 1.5 million km from Earth — roughly four times the distance to the Moon. At that distance it is around magnitude 28, billions of times too faint for any amateur equipment. By comparison, Hubble at 535km reaches magnitude 1.5 and is easily visible to the naked eye. Webb will never be visible from Earth's surface.
L2 is one of five gravitational balance points in the Sun-Earth system where a spacecraft can maintain a stable orbit using minimal fuel. At L2, the combined gravitational pull of the Sun and Earth exactly balances the centripetal force needed to orbit in sync with Earth. Webb sits about 1.5 million km directly behind Earth as seen from the Sun — keeping the Sun, Earth, and Moon all on the same side so its sunshield can block all three heat sources simultaneously and maintain its mirror at -233 degrees Celsius.
Hubble observes primarily visible and ultraviolet light from low Earth orbit at 535km. Webb observes infrared from L2 at 1.5 million km, with a 6.5m primary mirror — over six times Hubble's collecting area. Webb can see further back in time, detecting galaxies formed just 300 million years after the Big Bang. Hubble is visible to the naked eye on a clear night; Webb is not and never will be.
Webb's observation targets are publicly available through the Space Telescope Science Institute. Targets have included exoplanet atmospheres, early galaxy formation, star-forming nebulae like the Pillars of Creation, and solar system objects including Jupiter, Saturn, and Uranus. Webb produces roughly 50-100 gigabytes of science data per day.
The original design lifetime was 10 years. Precision launch and orbit insertion left Webb with significantly more fuel than expected — current estimates put the operational lifetime at 20 years or more. Webb launched on an Ariane 5 on 25 December 2021 and reached its L2 orbit in January 2022 after a 30-day journey.
Webb's TLE orbital data is published by Space-Track.org under NORAD ID 49954. Because Webb is not in a standard LEO orbit, its TLE is updated less frequently than satellites like the ISS. OrbitalNodes uses the latest available TLE to show Webb's approximate position in its halo orbit around L2.
