Crab Pulsar (B0531+21) is catalogued in this registry as a pulsar, held in the frame of Milky Way, from EM signals (curated).
Registry id PSR_CRAB ·
source layer signals ·
provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented
Exists from 1054-07-11 00:00:00 UTC (JD 2106216.5) — no end date is recorded.
Open Crab Pulsar (B0531+21) 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 | 12000 m (12 km) | no published uncertainty in this registry | EM signals (curated) |
| Temperature | 1000000 K | no published uncertainty in this registry | EM signals (curated) |
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.
