NGC 4696 is an elliptical galaxy of the Hubble type E1 / P with an active galaxy core in the constellation Centaur in the southern sky . It is estimated to be 124 million light years from the Milky Way and about 180,000 light years across. Together with PGC 43323 it forms an optical (?) Pair of galaxies. The galaxy is the eponymous member of the 79 galaxies counting NGC 4696 group ( LGG 298 ) and the brightest member of the Centaur galaxy cluster . The galaxy is surrounded by numerous dwarf galaxies .

Image of the dust filament around the core of NGC 4696 using the Hubble Space Telescope

A special property of NGC 4696 is a dust filament that is atypical for elliptical galaxies. Investigations by the Hubble space telescope, in which the filament was imaged using narrow and broadband filters , provide information about this.

The galaxies NGC 4677 , NGC 4683 , NGC 4706 , NGC 4709 are located in the same area of ​​the sky .

The Type Ia supernova SN 2017ejb was observed here.

The object was discovered on May 7, 1826 by the astronomer James Dunlop using a 9 inch telescope.
