Caldwell 51

Also Known as: IC 1613

Object Type: Irregular Dwarf Galaxy

Constellation: Cetus

Distance from Earth: : 2.38 million light years

Apparent Magnitude: 9.9

Coordinates: RA 01H 04M 47.8S DEC 02 deg 07 min 04 sec

Actual Size: 11,215 light years in diameter

Apparent Dimensions: 16.2 arc-minutes x 14.5 arc-minutes

Discovered by: IC 1613 was discovered by Max Wolf in 1906.

Description: IC 1613 is an irregular dwarf galaxy, 2.3 million light years from earth.
There is little dust associated with it which enables many background galaxies to be seen through it.
IC 1613 most closely resembles the nearby, transition-type dwarf galaxy Pegasus.
There are many blue star clusters and there is a bright HII region. IC 1613 is a member of the Local Group.
It has played an important role in the calibration of the Cepheid variable period-luminosity relation for estimating distances.

Other than the Magellanic Clouds, it is one of the few Local Group dwarf irregular galaxy where RR Lyrae-type variables have been observed; this factor, along with an unusually low abundance of interstellar dust both within IC 1613 and along the line of sight enable especially accurate distance estimates.
There are many faint galaxies close to IC 1613, catalogued as members of the group NOGG H 57
