UGC 4879, which is also known as VV 124, is the most isolated dwarf galaxy in the periphery of the Local Group. It is an irregular galaxy at a distance of 1.38 Mpc. Low-resolution spectroscopy yielded inconsistent radial velocities for different components of the galaxy, hinting at the presence of a stellar disk. There is also evidence of this galaxy containing dark matter.
Appearance
UGC 4879 is a transition type galaxy, meaning it has no rings (Denoted rs). It is also a spheroidal (dSph) galaxy, meaning it has a low luminosity. It has little to no gas or dust, and little recent star formation. It is also irregular, meaning it has no specific form.[4]
