NGC 4707 is an irregular galaxy in the constellation of Canes Venatici. It was discovered by John Herschel on 5 June 1834,[4] and was described by John Louis Emil Dreyer, the compiler of the New General Catalogue, as a "small, stellar" galaxy.[5]
NGC 4707 has a morphological type of Sm or Im, meaning that it is mostly irregular or has very weak spiral arms.[3] The galaxy was imaged by the Hubble Space Telescope in 2016. The image showed the galaxy had little to no signs of a central bulge or any prominent structures (typical of Magellanic-type spirals). However, the telescope could resolve many stars, as well as several turquoise-colored star forming regions.[6]
