NGC 1154 is a barred spiral galaxy located in the constellation Eridanus. It lies approximately 200 million light-years (62.26 Mpc) away from Earth. The galaxy was discovered by the American astronomer Francis Preserved Leavenworth on December 2, 1885. [1]
NGC 1154 is classified as an SB(rs)b galaxy, indicating that it is a barred spiral galaxy with a somewhat ring-like structure. It has an apparent magnitude of 13.6, making it relatively faint and observable primarily with large telescopes. [2]
Distance: ~200 million light-years (62.26 Mpc) - Right Ascension: 02h 56m 38.6s - Declination: −10° 21′ 47″
NGC 1154's coordinates place it within the celestial sphere of the constellation Eridanus, a region known for hosting numerous galaxies.
NGC 1154 is in close proximity to the galaxy NGC 1155, with which it may be interacting. A faint bridge of material appears to connect the two galaxies, suggesting tidal forces may be at play. [3]
NGC 1154 was discovered by Francis Leavenworth in 1885 as part of his deep-sky surveys. Modern observations have been carried out by surveys such as the Pan-STARRS and Sloan Digital Sky Survey (SDSS). [4]
One supernova has been observed in NGC 1154: SN 2011jp (type II-P, mag. 15.5) was discovered by Greg Bock on 27 December 2011. [5] [6]

NGC 1300 is a barred spiral galaxy located about 65 million light-years away in the constellation Eridanus. The galaxy is about 110,000 light-years across. It is a member of the Eridanus Cluster, a cluster of 200 galaxies, in a subgroup of 2-4 galaxies in the cluster known as the NGC 1300 Group. It was discovered by John Herschel in 1835.
NGC 1532, also known as Haley's Coronet, is an edge-on barred spiral galaxy located approximately 50 million light-years from the Solar System in the constellation Eridanus. The galaxy was discovered by James Dunlop on 29 October 1826.
NGC 1637 is an isolated, non-interacting intermediate spiral galaxy in the constellation Eridanus, about a degree to the WNW of the star Mu Eridani. It was discovered by German-British astronomer William Herschel on 1 February 1786. It is located at a distance of about 9.77 ± 1.82 Mpc (31.9 ± 5.9 Mly) from the Milky Way. The galaxy is inclined at an angle of 31.1° to the line of sight from the Earth and the long axis is oriented along a position angle of 16.3°.
NGC 2770 is a spiral galaxy in the northern constellation of Lynx, near the northern constellation border with Cancer. It was discovered by German-born astronomer William Herschel on December 7, 1785. J. L. E. Dreyer described it as, "faint, large, much extended 150°, mottled but not resolved, 2 stars to north". NGC 2770 was the target for the first binocular image produced by the Large Binocular Telescope.
NGC 51 is a lenticular galaxy in the constellation Andromeda. It has a diameter of 90,000 light-years. The galaxy was discovered on September 7, 1885, by Lewis Swift, who described it as "Pretty faint, pretty small, round, brighter middle."
NGC 210 is a barred spiral galaxy located roughly 67 million light-years from the Solar System in the constellation Cetus. It was discovered on October 3, 1785 by William Herschel and later added to the New General Catalogue.
NGC 6845 is an interacting system of four galaxies in the constellation Telescopium. The cluster has certain similarities with Stephan's Quintet. Its distance is estimated to be about 90 Mpc.
NGC 3198, also known as Herschel 146 is a barred spiral galaxy in the constellation Ursa Major. It was discovered by William Herschel on 15 January 1788. NGC 3198 is located in the Leo Spur, which is part of the Virgo Supercluster, and is approximately 47 million light years away.
NGC 157 is an intermediate spiral galaxy in the constellation of Cetus, positioned about 4° east of the star Iota Ceti. This galaxy can be viewed from suburban skies using a moderate-sized telescope. It was discovered on December 13, 1783 by William Herschel. The compiler of the New General Catalogue, John Louis Emil Dreyer noted that NGC 157 was "pretty bright, large, extended, between 2 considerably bright stars". It is a relatively isolated galaxy; the nearest other galaxy of comparable luminosity lies at a separation of 4.2 Mly (1.3 Mpc).
NGC 986 is a barred spiral galaxy in the southern constellation of Fornax, located about 76 million light-years away. It was discovered on August 5, 1826, by the Scottish astronomer James Dunlop, who described it as a "faint nebula, of an irregular round figure". The galaxy has an angular size of 3′.8 × 1′.9 with a visual magnitude of 10.9. It belongs to the Fornax Cluster of galaxies. This galaxy has a nearby companion, NGC 986A, at an angular separation of 17′, corresponding to a projected separation of 110 kpc. The two appear unconnected.
NGC 521, also occasionally referred to as PGC 5190 or UGC 962, is a barred spiral galaxy located approximately 224 million light-years from the Solar System in the constellation Cetus. It was discovered on 8 October 1785 by astronomer William Herschel.
NGC 1310 is a barred spiral galaxy located in the southern constellation of Fornax. It was discovered by English astronomer John Herschel on 22 October 1835.
NGC 782 is a barred spiral galaxy located in the constellation Eridanus about 160 million light-years from the Milky Way. It was discovered by British astronomer John Herschel in 1834.
NGC 1325 is a flocculent spiral galaxy situated in the constellation of Eridanus. Located about 75 million light years away, it is a member of the Eridanus cluster of galaxies, a cluster of about 200 galaxies. It was discovered by William Herschel on 19 December 1799.
NGC 1100 is a spiral galaxy located around 235 million light-years away in the constellation Eridanus.

NGC 1100 is not known to have much star formation, and is not known to have an active galactic nucleus.
NGC 1819 is a lenticular galaxy in the constellation of Orion. It was discovered on December 26, 1885, by American astronomer Lewis A. Swift. This galaxy is located at a distance of 197.4 million light-years (60.53 Mpc) from the Milky Way, and is receding with a heliocentric radial velocity of 4,483 km/s.
NGC 945 is a barred spiral galaxy in the constellation Cetus, located south of the celestial equator. It is estimated to be 200 million light-years from the Milky Way, and about 135,000 light-years in diameter. The object was discovered by astronomer William Herschel on November 28, 1785. It is within close proximity to NGC 948, with which it forms a gravitationally bound pair of galaxies. In the same area of the sky there are the galaxies NGC 942, NGC 943, NGC 950, and IC 230.
NGC 3914 is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 6466 ± 25 km/s, which corresponds to a Hubble distance of 95.38 ± 6.69 Mpc. However, six non-redshift measurements give a distance of 81.2 ± 2.8 Mpc. The galaxy was discovered by German-British astronomer William Herschel on 13 April 1784.
NGC 5876 is a barred spiral galaxy in the constellation of Boötes. Its velocity with respect to the cosmic microwave background is 3325 ± 5 km/s, which corresponds to a Hubble distance of 49.05 ± 3.43 Mpc. However, three non redshift measurements give a distance of 65.6 ± 0.346 Mpc. The galaxy was discovered by American astronomer Lewis Swift on 11 June 1885. Swift observed the galaxy again on August 27, 1888, and not realizing that he had already observed it, entered the galaxy into the Index Catalogue as IC 1111.
