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 as part of his deep-sky surveys.[1] Modern observations have been carried out by surveys such as the Pan-STARRS and Sloan Digital Sky Survey (SDSS).[2] It has an apparent magnitude of 13.6, making it relatively faint and observable primarily with large telescopes.[3]
NGC 1154 is classified as an SB(rs)b galaxy, indicating that it is a barred spiral galaxy with a somewhat ring-like structure and closely wound spiral arms. It is positioned close 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.[4][better source needed]
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]
