Cepheus1 is catalogued in this registry as a galaxy, held in the frame of CMB Rest Frame, from Local Volume galaxies (Karachentsev+ 2013 UNGC).
Registry id LVG_CEPHEUS1 ·
source layer lvg ·
provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented
Open Cepheus1 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.
| Quantity | Value | Uncertainty | Source |
|---|---|---|---|
| Radius | 1.90078×10^20 m (1.27059×10^9 au) | no published uncertainty in this registry | Local Volume galaxies (Karachentsev+ 2013 UNGC) |
| Mass | 5.73611×10^39 kg | no published uncertainty in this registry | Local Volume galaxies (Karachentsev+ 2013 UNGC) |
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.

| Coverage | 864 galaxies within ~11 Mpc on the catalog's ADOPTED published distances (method named per record: TRGB · Cepheids · SBF · Tully–Fisher · brightest stars · membership · Hubble-flow rows labelled redshift-derived); σ_d carried where the paper's distance table publishes an error (298). 4D honesty (A5): radial velocity measured, tangential unmeasured — NO drift modelled. Local Group members (D ≤ 1.0 Mpc, the measured zero-velocity radius R0 = 0.96 ± 0.03 Mpc, Karachentsev et al. 2009) parent to the Local Group anchor (69); the rest are field galaxies in the CMB rest frame (795).
