Epsilon Eridani

Epsilon Eridani is catalogued in this registry as a star, held in the frame of Milky Way, from Local universe (curated).

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

Open Epsilon Eridani 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.

Sources disagree about this object

The registry keeps every source's value rather than choosing one and discarding the rest. If you quote a figure below, quoting it alone would hide a real disagreement between catalogues.

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.
