NGC 4102 is an intermediate[9] barred spiral galaxy located in the northern constellation of Ursa Major.

[11] This galaxy is located at a distance of 60[5] million light years and is receding with a heliocentric radial velocity of 837 km/s.

[6] The morphological class of NGC 4102 is SABab[3] or SAB(s)b?,[10] which is a spiral galaxy with a bar-like feature around the core (SAB), no inner ring structure (s), and moderately tightly-wound spiral arms ('ab' or 'b').

[13] An outflow of hydrogen has been detected, extending outward to the northwest as far as 6.3 kpc (21 kly) from the nucleus.

[14] The core of NHC 4102 is almost certainly an active galactic nucleus (AGN),[15] which indicates it has a supermassive black hole (SMBH) that is generating energy by accreting material.
