NGC 1023 is the nearest lenticular galaxy to the milkyway at a distance of 34 million lightyears and the brightest member of a galaxy group with prominent members like NGC 891 and NGC 925.
The most obvious companian is NGC 1023A to the left, which is the reason why both objects are catalogued as Arp 135. Through the disk of luminous material, the bright central bulge and a bar can be seen, thats why NGC 1023 is classified as SB0.
