IC 3505 is a barred spiral galaxy[1] located 640 million light-years[2] away from the Solar System in the Coma Berenices constellation.[3] With an apparent size of 0.95 by 0.35 arcmin, IC 3505 has an estimated diameter of 170,000 light-years, making it slightly larger compared to the Milky Way.[2] It is categorized as a LINER galaxy[4] with an active galactic nucleus[5] emitting weak emission-lines.[6]

IC 3505 was discovered by Royal Harwood Frost on May 7, 1904.[7] According to Frost when he saw the object for the first time, he listed it as a type SBc at right ascension "12 34 10.3" and declination "+15 58 07".[7] Despite being listed in the Virgo Cluster catalogue as VCC 1542, it is not part of the Virgo Cluster but a background galaxy.[8]

Two supernovae have been discovered in IC 3505. SN 2019iaz (Type Ia, mag: 19.6) was discovered on June 21, 2019, by C. Fremling from Caltech on behalf on Zwicky Transient Facility (ZTF)[9] and AT 2023gpz (unknown, mag: 20.2) which was discovered by K. De (also from ZTF) on April 21, 2023.[10]
