NGC 5707 is an edge-on spiral galaxy in the constellation Bear Keeper (Bootes). It is located around 2 arc minutes west-southwest of the star HD 128941 ( SAO 29224 , 7 mag). Immediately on its northern edge is another, much less bright galaxy ( PGC 52269 ), which is likely to be a background object .
The galaxy was discovered in 1878 by the astronomer Lewis A. Swift using his 16-inch lens telescope and was later included in his New General Catalog by Johan Dreyer .
