NGC 4835 is a 11.6 mag bright bar spiral galaxy of the Hubble type SBbc in the constellation Centaur in the southern sky . It is estimated to be 160 million light years from the Milky Way and has a diameter of about 85,000 ly.
The object was discovered on June 3, 1834 by John Herschel with an 18-inch reflector telescope, who described it as "bright, large, much elongated, gradually a little brighter in the middle, 90 arcseconds long, 25 arcseconds broad". On a second observation he noted "faint, much elongated, very gradually brighter in the middle, 25 arcseconds"; He commented on his last observation with “faint, much elongated in pos 147; very slightly brighter in the middle; 2 ′ long. Taken beyond the meridian, and out of reach in RA ".
