Explore Proxima Centauri in COSMOS
A nearby Gaia source identified by SIMBAD as Proxima Centauri. Its depth and motion here are derived only from Gaia DR3 astrometry. Its position in the explorer is a measured Gaia DR3 point, not an illustration, and the distance comes from its parallax.

What opens when you follow this link
COSMOS opens in the same continuous 3D scene and moves the camera to Proxima Centauri. Nothing reloads, and the breadcrumb trail stays clickable for the way back outward through the Solar System, the measured stellar catalogue and the Galactic view.
If your browser cannot run WebGL2, this page is still the useful part: it carries the identity, the measured values and the provenance, in text.
