Coddington

There are discussions on whether or not this is a nebula or a galaxy, however it is known to be in a spiral shape. It is mostly called a dwarf galaxy because if its small size. Located in Ursa Minor and later given the name the Coddington Nebula. Named after Eward Coddington who was an astronomer who discovered it in 1898.

This Nebula is about 11,700 light-years away from Earth, and the Angular size of the object is 7.6 arcminutes and the Linear Size is 26 lightyears. Colors in this image inclide lots of green and some yellows and reds and the very little blue dots. Better Pictures have been taken of this galaxy. It is shown tilted and not going up and down or side to side.
