NGC 4444
Galaxy in the constellation Centaurus
From Wikipedia, the free encyclopedia
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]
