    1703 Barry, provisional designation 1930 RB, is a 10-kilometer sized stony asteroid and suspected tumbler from the inner regions of the asteroid belt. It was discovered by German astronomer Max Wolf at Heidelberg Observatory on 2 September 1930.[10] In the same month, it was independently discovered by Dutch astronomer Hendrik van Gent and Soviet astronomer Evgenii Skvortsov at their observatories in Johannesburg and Crimea, respectively.[2]

    The relatively bright S-type asteroid with an albedo of about 0.28 is a member of the Flora family, a large group that accounts for up to 5% of all main-belt asteroids.[4][5][6] It orbits the Sun at a distance of 1.8–2.6 AU once every 3.30 years (1,204 days). Its orbit shows an eccentricity of 0.17 and is tilted by 5 degrees to the plane of the ecliptic.[1] Photometric observations reported in 2007 showed a leisurely rotation period of 107.1±0.5 hours with a brightness variation of 0.5 magnitude. It may have a non-principal axis rotation.[7] However, no follow-up measurements have since confirmed its tumbling motion.[3]

    The asteroid is named after Vincentian priest Roger Barry (1752–1813), the Court Astronomer of Grand Duchy of Baden at the Mannheim Observatory in 1788. The Heidelberg Observatory is a direct successor to the old Mannheim Observatory.[2]
