NGC 1154 is a barred spiral galaxy located in the constellationEridanus. It lies approximately 200 million light-years (62.26 Mpc) away from Earth. The galaxy was discovered by the American astronomerFrancis 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 galaxyNGC 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 thePan-STARRS andSloan Digital Sky Survey (SDSS).[4]
Onesupernova 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]
