De Vaucouleurs Atlas Description:
The spiral pattern is well-defined and slightly asymmetric. As the arms spiral inward, they appear to wind into a weak inner pseudoring . It is unclear whether this feature has any dynamical significance; it could be merely a result of perspective on an open spiral pattern. There is no bar evident in the Atlas image.
NGC 3893 has a small companion, NGC 3896 , close to the southeast. The slight asymmetry in NGC 3893 could be the result of an interaction between the two galaxies.
