M35 (NGC 2168)

M35 (NGC 2168) is catalogued in this registry as a cluster, held in the frame of Milky Way, from Naked-eye deep-sky objects (curated).

Registry id DS_M35 · source layer deepsky · provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented

Open M35 (NGC 2168) 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.

The catalogue's own note

Open cluster — naked-eye deep-sky object. Distance 906 pc. Integrated V ≈ 5.1. Extent: 19.1′ (r50, CG2020) ≈ 5.0 pc radius at the published distance. A naked-eye cluster at the feet of Gemini. Distance + centroid + r50: Gaia DR2 cluster census [Cantat-Gaudin et al. 2020].

How it enteredCurated data-as-code (src/ingest/catalogs/deepsky.ts)
Coverage31 classical naked-eye deep-sky objects — 20 open clusters (Pleiades · Hyades · Beehive · Ptolemy · Double Cluster · NGC 6231 …), 9 globular clusters (ω Cen · 47 Tuc · M13 …), 2 nebulae (Orion · Carina); names carry M/NGC/IC designations so the sky-culture deep-sky join attaches cultural names
