Alchiba

Alchiba is catalogued in this registry as a star, held in the frame of Milky Way, from Gaia DR3 — local star field 4D.

Registry id GAIA_3489338019475637760 · source layer gaia · provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented

Open Alchiba in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.

Each row carries its own uncertainty and its own source. Where a row says no uncertainty is published, that is what the catalogue says — it is not a claim that the value is exact.

Coverage36,835 stars ≤50 pc, σ_d/d<1% (I15 in-query); 26,777 with radial velocity; cross-joined to the exoplanet hosts (dedup + teff corroboration). Positions are REAL positions at the simulated instant, not the sky as seen from Earth: each catalogue position is displaced along the star's own measured velocity by (J2000 − catalogue epoch) PLUS the light-travel time d/c, since a catalogue records where a star APPEARED. A star with no measured motion is not displaced at all.
