NGC 4298 is a flocculent [3] [4] [5] [6] spiral galaxy located about 53 million light-years away [7] in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 8, 1784 [8] and is a member of the Virgo Cluster. [9] [10] [11]
NGC 4298 may harbor an intermediate-mass black hole with an estimated mass ranging from 20,000 (2×104 M☉) to 500,000 (5×105 M☉) solar masses. [12]
NGC 4298 appears to form a pair with [13] [14] [15] and appears to interact with NGC 4302. [13] [2] [14] [16] [15] [17] [18] [4] Evidence for an interaction between the two galaxies are that NGC 4298 exhibits a lopsided, asymmetrical distribution of stars, [4] [16] [15] a tidal bridge that connects it to NGC 4302, [18] [17] [2] a prodigious rate of star formation [19] and an HI-tail. However, the tail is also the result of ram pressure. [3]
The two galaxies are separated from a projected distance of ~36,000 ly (11 kpc ). [20] [15] [3]
The presence of a truncated gas disc, [3] [4] an asymmetric 6 cm polarized radio continuum distribution, [13] an HI-tail, [3] and asymmetries of gas in a similar direction as the ram pressure stripped gas in NGC 4302 suggest that NGC 4298 is undergoing ram pressure. [2]
Messier 90 is an intermediate spiral galaxy exhibiting a weak inner ring structure about 60 million light-years away[a] in the constellation Virgo. It was discovered by Charles Messier in 1781.
NGC 4216 is a metal-rich intermediate spiral galaxy located not far from the center of the Virgo Cluster of galaxies, roughly 55 million light-years away. It is seen nearly edge-on.
The Eyes Galaxies are a pair of galaxies about 52 million light-years away in the constellation Virgo. The pair are members of the string of galaxies known as Markarian's Chain.
NGC 4450 is a spiral galaxy in the constellation Coma Berenices.
NGC 4323 is a lenticular or dwarf elliptical galaxy located about 52.5 million light-years away in the constellation Coma Berenices. The galaxy was discovered in 1882 by astronomer Wilhelm Tempel and is a member of the Virgo Cluster.
NGC 4651 is a spiral galaxy located in the constellation of Coma Berenices that can be seen with amateur telescopes, at a distance not well determined that ranges from 35 million light years to 72 million light years.
NGC 4654 is an intermediate spiral galaxy in the constellation of Virgo at a distance of 55 million light years from the Milky Way that can be spotted with amateur telescopes.
NGC 4535 is a barred spiral galaxy located some 54 million light years from Earth in the constellation Virgo. It is a member of the Virgo Cluster of galaxies and is located 4.3° from Messier 87. The galactic plane of NGC 4535 is inclined by an angle of 43° to the line of sight from the Earth. The morphological classification of NGC 4535 in the De Vaucouleurs system is SAB(s)c, which indicates a bar structure across the core (SAB), no ring (s), and loosely wound spiral arms (c). The inner part of the galaxy has two spiral arms, which branch into multiple arms further away. The small nucleus is of type HII, meaning the spectrum resembles that of an H II region.
NGC 4457 is an intermediate spiral galaxy located about 55 million light-years away in the constellation of Virgo. It is also classified as a LINER galaxy, a class of active galaxy defined by their spectral line emissions. NGC 4457 Is inclined by about 33°. It was discovered by astronomer William Herschel on February 23, 1784. Despite being listed in the Virgo Cluster Catalog as VCC 1145, NGC 4457 is a member of the Virgo II Groups which form an extension of the Virgo cluster.
NGC 4522 is an edge-on spiral galaxy located about 60 million light-years away within the Virgo Cluster in the constellation Virgo. NGC 4522 is losing its molecular gas though ram-pressure stripping as it plows though the cluster at a speed of more than 10 million kilometres per hour. The galaxy was discovered by astronomer John Herschel on January 18, 1828.
NGC 4607 is an edge-on spiral galaxy located about 56 million light-years away in the constellation Virgo. NGC 4607 was discovered by astronomer R. J. Mitchell on April 24, 1854. The galaxy is a member of the Virgo Cluster.
NGC 4660 is an elliptical galaxy located about 63 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer William Herschel on March 15, 1784 and is a member of the Virgo Cluster.
NGC 4222 is an edge-on spiral galaxy located about 60 million light-years away in the constellation Coma Berenices. It was discovered by astronomer William Herschel on April 8, 1784 and is often misidentified as IC 3087. NGC 4222 is a member of the Virgo Cluster and is a companion of NGC 4216 which lies about 180,000 ly (56 kpc) away. Despite this, the two galaxies are not interacting.
NGC 4294 is a barred spiral galaxy with flocculent spiral arms located about 55 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer William Herschel on March 15, 1784 and is a member of the Virgo Cluster.
NGC 4299 is a featureless spiral galaxy located about 55 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on March 15, 1784 and is a member of the Virgo Cluster.
NGC 4302 is an edge-on spiral galaxy located about 55 million light-years away in the constellation Coma Berenices. It was discovered by astronomer William Herschel on April 8, 1784 and is a member of the Virgo Cluster.
NGC 4305 is a dwarf spiral galaxy located about 100 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer John Herschel on May 2, 1829. Although considered to be a member of the Virgo Cluster, its high radial velocity and blue luminosity suggest it is in fact a background galaxy. The galaxy has a nearby major companion; NGC 4306.
NGC 4312 is an edge-on unbarred spiral galaxy located about 55 million light-years away in the constellation Coma Berenices. It was discovered by astronomer William Herschel on January 14, 1787. NGC 4312 is a member of the Virgo Cluster and is a LINER galaxy.
NGC 4324 is a lenticular galaxy located about 85 million light-years away in the constellation Virgo. It was discovered by astronomer Heinrich d'Arrest on March 4, 1862. NGC 4324 has a stellar mass of 5.62 × 1010M☉, and a baryonic mass of 5.88 × 1010M☉. The galaxy's total mass is around 5.25 × 1011M☉. NGC 4324 is notable for having a ring of star formation surrounding its nucleus. It was considered a member of the Virgo II Groups until 1999, when its distance was recalculated and it was placed in the Virgo W Group.
NGC 4123 is a modest-sized, strongly-barred spiral galaxy located 75 million light-years away in the equatorial constellation of Virgo. It was discovered February 25, 1784 by William Herschel. This is a member of the Virgo cluster, and it belongs to a group of three galaxies. A companion galaxy, NGC 4116, lies at an angular separation of 14′ to the southwest. There is no indication of an interaction between the two galaxies. The third member of the group is NGC 4179.
