    1925 Franklin-Adams, provisional designation 1934 RY, is a main belt asteroid with an orbital period of 1489 days (4.08 years). It was discovered on 9 September 1934 by Dutch astronomer Hendrik van Gent at the Leiden Southern Station, annex to the Johannesburg Observatory in South Africa.[1]

    It is named after English amateur astronomer John Franklin-Adams (1843–1912), who created one of the earliest detailed, photographic atlases of the complete night sky (the Franklin-Adams plates or charts).[3] He later donated his 25-cm Franklin-Adams Star Camera (Franklin-Adams photographic refractor) to the Johannesburg Observatory, which lead to the discovery of Proxima Centauri.[2]
