NGC 4567 and NGC 4568 (nicknamed the Butterfly Galaxies [4] or Siamese Twins [NB 1] [5]) are a set of unbarred spiral galaxies about 60 million light-years away [1] in the constellation Virgo. They were both discovered by William Herschel in 1784. They are part of the Virgo Cluster of galaxies.

NGC 4564 is an elliptical galaxy located about 57 million light-years away [2] in the constellation Virgo. [3] NGC 4564 was discovered by astronomer William Herschel on March 15, 1784. [4] The galaxy is also a member of the Virgo Cluster. [5] [6] NGC 4564 has an estimated population of 213 ± 31 globular clusters. [7]
NGC 4567 and NGC 4568 Also known as the Butterfly Galaxies , NGC 4567 and 4586 are two unbarred spiral galaxies that are colliding. The pair were first discovered by astronomer William Herschel in 1784, but did not earn their name until observer Ralph Copeland called them the Siamese Twins in the late 1800s due to their almost identical shape ...

NGC 4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy. [6] Much speculation exists in literature as to the nature of the central bulge. In the absence of clear-cut dynamical data on the motions of stars in the bulge, the photometric data alone cannot adjudge among various options put forth.
The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
