## At a glance

- **WHAT IT IS:** Millisecond pulsar
- **HOW FAR:** 29 651 ly — The light arriving now left it that long ago.

## Properties

| Quantity | Value |
| --- | --- |

## 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 |
| --- | --- |
| Spin period | 0.00254474 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 | 0.007 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) | −0.15 ±0.03 mas/yr |
| Proper motion (Dec) | −2.67 ±0.03 mas/yr |
| Position epoch | J2019.552 |
| Dispersion measure | 26.5 pc/cm³ |

### THE ORBIT

The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.

| Field | Value |
| --- | --- |
| Binary orbit model | BT |

### OTHER NAMES AND NUMBERS

The identifiers other catalogues file this object under, for anyone joining this data to theirs.

| Field | Value |
| --- | --- |
| Associated with | GC:M3(NGC5272) |
