# IC1166 NED02

IC1166 NED02 is a barred spiral [galaxy](https://spacecatalog.org/galaxies) SBb in the constellation [Corona Borealis](https://spacecatalog.org/constellation/corona-borealis), 1.075 Gly from Earth, shining at apparent magnitude 17.07 (B). Other catalogues list it as 2MASX J16020881+2619316, PGC 1771884 and SDSS J160208.82+261931.1.

## At a glance

- **WHAT IT IS:** Barred spiral galaxy
- **HOW FAR:** 1.075 Gly — A luminosity distance, from its redshift — how faint it looks. The light itself left 964 million years ago.
- **HOW BIG ON THE SKY:** 25″ — Small enough that the full Moon would cover it several times over.
- **HOW BRIGHT (B):** 17.07 — Faint: it takes a large telescope.
- **WHERE TO LOOK:** [Corona Borealis](https://spacecatalog.org/constellation/corona-borealis) — 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) | 17.07 |
| Apparent magnitude (J) | 14.14 |
| Apparent magnitude (H band) | 13.40 |
| Apparent magnitude (K) | 12.87 |
| Surface brightness | 23.47 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 |
| --- | --- |
| Radial velocity | 21 019 km/s |
| Redshift (z) | 0.07275 |
| Redshift (z, CMB frame) | 0.0730312 |
| Major axis | 0.41′ |
| Minor axis | 0.28′ |
| Position angle | 152° |

### OTHER NAMES AND NUMBERS

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

| Field | Value |
| --- | --- |
| OpenNGC type code | G |
