Where is Euclid right now?

Orbital Radar tracks Euclid in real time from NASA JPL Horizons ephemeris data, showing its live distance from Earth and the Sun, current speed and one-way signal delay, updated every 60 seconds. ESA's dark-universe telescope at Sun–Earth L2 — surveying billions of galaxies across a third of the sky to map how dark matter and dark energy have shaped the cosmos over the past 10 billion years.

How far is Euclid from Earth?

Euclid's distance from Earth changes constantly as both bodies move through the solar system. The live figure — in kilometres and astronomical units (AU), with the matching light-travel (signal) time — is shown at the top of this page and refreshes automatically.

Mapping the Dark Universe

Euclid is ESA's mission to investigate the two greatest mysteries in cosmology — dark matter and dark energy, which together make up about 95% of the universe. From Sun–Earth L2, its 1.2-metre telescope images billions of galaxies across more than a third of the sky, measuring their shapes and distances to reconstruct how cosmic structure has grown over the past 10 billion years.

A Cosmic Time Machine

By charting the subtle distortions in galaxy shapes caused by gravitational lensing, Euclid maps the invisible scaffolding of dark matter and tests whether dark energy is truly constant or changing over time. Its first major data release in 2026 already delivered one of the largest galaxy catalogues ever produced.
