    1116 Catriona is a main-belt asteroid orbiting the Sun at a distance of 2.25 to 3.59 AU. It was discovered by Cyril Jackson on April 5, 1929, at Johannesburg Union Observatory, South Africa. Its provisional designation was 1929 GD. The relatively bright asteroid is approximately 39 kilometers in diameter and completes one revolution once every 5.00 years.[1]

    It was probably named after Catriona, the 1893-novel by Robert Louis Balfour Stevenson (1850–1894), Scottish poet, novelist, and travel writer.[2]
