NGC 4444 is an intermediate spiral galaxy in the constellation Centaurus. The morphological classification places it midway on the continuum between a barred spiral (SB) and an unbarred spiral (SA), with an inner region that lies between a ring-like (r) and a purely spiral form (s), and medium- (b) to loosely wound (c) outer spiral arms. This makes it a hybrid ringed, barred spiral galaxy. [6] It has an angular size of 2.4 × 1.6 arcminutes [5] and the estimated mass M is given log  M = 9.76, yielding 5.8 billion solar masses. [4]
