NGC 4444 | |
---|---|
Observation data (J2000 epoch) | |
Constellation | Centaurus |
Right ascension | 12h 28m 36.419s [1] |
Declination | −43° 15′ 42.15″ [1] |
Redshift | 0.009771 [1] |
Heliocentric radial velocity | 2915 km/s [1] |
Distance | (38.8 ± 5.7 M pc) [2] |
Characteristics | |
Type | SAB(rs)bc [3] |
Mass | 5.8 × 109 [4] M☉ |
Apparent size (V) | 2′.4 × 1′.6 [5] |
Other designations | |
MCG -07-26-007, PGC 41043 [1] |
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]
