Nushagak is catalogued in this registry as a star, held in the frame of Milky Way, from NASA Exoplanet Archive (pscomppars).
Registry id EXOS_HD_17156 ·
source layer exoplanets ·
provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented
Open Nushagak 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.

Planet host (1 planets). Space velocity MEASURED (proper motion + radial velocity). Position displaced along that velocity by the light-travel time d/c (the archive reports where the host APPEARED); no catalogue epoch is published per row, so no epoch term is applied.
