IC 1613, Caldwell 51 Facts Irregular Dwarf Galaxy in Cetus

IC 1613, Caldwell 51 is an irregular dwarf galaxy object of interest in space. It lies at a distance of 2.38 MLy light years away in the constellation of Cetus.

IC 1613, Caldwell 51 was discovered in 1906 by Max Wolf.

The Irregular Dwarf Galaxy's location is 1h 4m 47.8 (R.A.) and +2d 07` 04 (Dec.). Its Visual (Apparent) Brightness is 10.00 Magnitude . The object can not be seen by the naked eye, you need a telescope to see it.

It is referred to as an irregular dwarf galaxy as it has very little shape compared to other more structured elliptical and spiral. The reason for the irregular is believed to be because of gravitational forces of other galaxies nearby. Helix

The galaxy is a member of the local group of galaxies and it polayed a big role in estimating the distances to nearby distances. Along with the two Magellanic Clouds, it is the only other local galaxy where RR Lyrae type stars have been observed. RR Lyrae's are pulsating type variable stars. In addition to RR Lyrae, a Wolf-Rayet star has also been detected inside the galaxy.
