# NGC 6387

NGC 6387 is a barred spiral [galaxy](https://spacecatalog.org/galaxies) SBb in the constellation [Draco](https://spacecatalog.org/constellation/draco), shining at apparent magnitude 16.81 (V). Other catalogues list it as 2MASX J17282376+5732428, IRAS 17275+5735 and IRAS F17275+5734, among 10 designations in total. It was discovered in 1886.

## At a glance

- **WHAT IT IS:** Barred spiral galaxy
- **HOW BIG ON THE SKY:** 19″ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (V):** 16.81 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Draco](https://spacecatalog.org/constellation/draco) — The patch of sky it sits in, as seen from Earth.

## 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 |
| --- | --- |
| Hubble type | SBb |

### 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 |
| --- | --- |
| Apparent magnitude (B) | 15.20 |
| Apparent magnitude (V) | 16.81 |
| Surface brightness | 21.51 mag/arcsec² |

### 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 |
| --- | --- |
| Major axis | 0.31′ |
| Minor axis | 0.15′ |
| Position angle | 63° |

### WHEN IT WAS FOUND

Who first saw it, from where, and by what method.

| Field | Value |
| --- | --- |
| Discovered by | Lewis A. Swift |

### OTHER NAMES AND NUMBERS

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