NGC 484 is an elliptical galaxy in the constellation Tucana. [2] It is located approximately 218 million light-years from Earth and was discovered on October 28, 1834 by astronomer John Herschel. [3] [4]
NGC 4639 is a barred spiral galaxy located in the equatorial constellation of Virgo. It was discovered by German-born astronomer William Herschel on April 12, 1784. John L. E. Dreyer described it as "pretty bright, small, extended, mottled but not resolved, 12th magnitude star 1 arcmin to southeast". This is a relatively nearby galaxy, lying approximately 72 million light-years away from the Milky Way. It is a companion to NGC 4654, and the two appear to have interacted roughly 500 million years ago. NGC 4639 is a member of the Virgo Cluster.
NGC 7012 is a large, bright elliptical galaxy located about 380 million light-years away from Earth in the constellation Microscopium. NGC 7012 was discovered by astronomer John Herschel on July 1, 1834.
NGC 471 is a lenticular galaxy located about 168 million light-years away from Earth in the constellation Pisces. It was discovered by the German astronomer Albert Marth on November 3, 1864.
NGC 4313 is an edge-on spiral galaxy located about 50 million light-years away in the constellation Virgo. It was discovered by astronomer William Herschel on March 15, 1784. NGC 4313 is a member of the Virgo Cluster and is classified as LINER and as a Seyfert galaxy.
NGC 995 is a lenticular galaxy located in the constellation Andromeda about 178 million light years from the Milky Way. It was discovered by the French astronomer Édouard Stephan in 1871.

NGC 940 is a lenticular galaxy in the constellation Triangulum. It is estimated to be 222 million light-years from the Milky Way and has a diameter of approximately 80,000 ly. NGC 940 was discovered by Heinrich d'Arrest.
NGC 530, also known as IC 106, is a lenticular galaxy in the constellation Cetus. It is approximately 226 million light years from the Milky Way and has a diameter of around 100,000 light years. The object was discovered on November 20, 1886, by the American astronomer Lewis A. Swift, who listed it as NGC 530, and rediscovered on November 16, 1887, by Guillaume Bigourdan, who listed it as IC 106.
NGC 912 is a compact lenticular galaxy located in the constellation Andromeda about 197 million light years from the Milky Way. It was discovered by French astronomer Édouard Stephan in 1878.
NGC 913 is a lenticular galaxy located in the constellation Andromeda about 224 million light years from the Milky Way. It was discovered by French astronomer Édouard Stephan in 1878.
NGC 998 is a spiral galaxy in the constellation Cetus. It is estimated to be 294 million light years from the Milky Way and has a diameter of approximately 90,000 ly. Together with NGC 997, it forms a gravitationally bound pair of galaxies. NGC 998 was discovered by astronomer Albert Marth on 10 November 1863 using a 48-inch telescope.
