    1132 Hollandia, provisional designation 1929 RB1, is an eccentric, stony asteroid from the middle region of the asteroid belt, about 27 kilometers in diameter. It was discovered by Dutch astronomer Hendrik van Gent at the Leiden Southern Station, annex to the Johannesburg Observatory, South Africa, on 13 September 1929.[10]

    The S-type asteroid orbits the Sun at a distance of 1.9–3.4 AU once every 4 years and 5 months (1,610 days). Its orbit shows a high eccentricity of 0.28 and is tilted by 7 degrees to the plane of the ecliptic. It has a rotation period of about 5.4 hours.[7][8][9] According to the space-based surveys carried out by the Japanese Akari and the Wide-field Infrared Survey Explorer satellites, the body's geometric albedo is about 0.13.[4][5][6]

    The minor planet was named after the Latin name for Holland, a region in the Netherlands.[2]
