IC 1613, aka UGC 668, DDO 8, PGC 3844, Caldwell 51 is an irregular dwarf galaxy in the constellation Cetus near the star 26 Ceti. It is approaching Terra at 234 km/s.
IC 1613 is a member of the Local Group. Other than LMC and SMC, it is the only Local Group dwarf irregular galaxy where RR Lyrae-type variables have been observed.
The dominant population of this galaxy has an age of ~7 Gyr (gigayears = 109 or 1,000,000,000 Terran years). Its evolutionary history may be similar to that of the Pegasus Dwarf Irregular Galaxy. Both galaxies are classified as Ir V in the DDO system. Astromomers have found five cepheids of Population II in IC 1613, giving self-evident support for the existence of a very old stellar population component of IC 1613.
There are Ancient gates in IC1613 that allow traffic to and from Canis Major and Pieces Dwarf. They are:
Canis Major → IC 1613
Pieces Dwarf → IC1613 → Pieces Dwarf
Canis Major → Pieces Dwarf
