| --- | --- |
| CLASS | Pulsar |
| DISTANCE FROM EARTH | 4951 ly — by dispersion measure through the YMW16 electron-density model |
| CONSTELLATION | Centaurus |

## Catalogue data

### WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

| Field | Value |
| --- | --- |
| Surface magnetic field | 1.75×10¹² G |
| Spin period | 0.364715 s |
| Spin-down rate | 8.23×10⁻¹⁵ s/s |
| Characteristic age | 702 416 yr |
| Spin-down luminosity | 6.69×10³³ erg/s |

### HOW BRIGHT IT IS

What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.

| Field | Value |
| --- | --- |
| Radio flux at 1400 MHz | 6 mJy |

### WHERE IT IS AND HOW IT MOVES

Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.

| Field | Value |
| --- | --- |
| Proper motion (RA) | 10 ±17 mas/yr |
| Proper motion (Dec) | 43 ±9 mas/yr |
| Position epoch | J2021.507 |
| Position known to | 0.15″ |
| Dispersion measure | 85.11 pc/cm³ |
