NGC 4444
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. It has an angular size of and the estimated mass ''M'' is given log ''M'' = 9.76, yielding solar masses. ==References==
