Physical characteristics
NGC 4477 has a very well-defined bar which is imbedded within an extensive lens-like envelope. It has a fairly sharp edge and is slightly enhanced near the rim, and is classified as a ring-like feature. Surrounding the ring, two broad, diffuse incomplete arcs appear to bracket the galaxy around the bar. It is suggested that NGC 4477 has a highly evolved double ring morphology. Also, both ring features are exceedingly washed out.[3]
