IC 3505 was discovered by Royal Harwood Frost on May 7, 1904.{{Cite web |title=Index Catalog Objects: IC 3500 - 3549 |url=https://cseligman.com/text/atlas/ic35.htm#ic3505 |access-date=2024-04-22 |website=cseligman.com}} 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". Despite being listed in the Virgo Cluster catalogue as VCC 1542, it is not part of the Virgo Cluster but a background galaxy.{{Cite journal |last1=Binggeli |first1=B. |last2=Sandage |first2=A. |last3=Tammann |first3=G.
