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'). However, the bar in this galaxy is considered particularly small for galaxies of this class.[10] The
galactic plane is inclined at an angle of 56°±2° to the line of sight from the Earth.[12] NGC 4102 has a region of intense star formation in the nuclear region, known as a
starburst region.[6] This volume is 1,000 ly (310 pc) in diameter containing some 3 billion
solar masses.[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]
