1148 Rarahu is a main belt asteroid orbiting the Sun. Approximately 33 kilometers in diameter, it makes a revolution around the Sun once every 5 years. It completes one rotation once every 6 hours. It was discovered by Alexander Nikolaevich Deutsch on July 5, 1929.[1] On July 28, it was independently discovered by Cyril V. Jackson and H.E. Wood in Johannesburg, South Africa. Rarahu is the Tahitian name for a girl, taken from the novel Le mariage de Loti (Loti's Marriage) by Louis Marie Julien Viaud, a.k.a. Pierre Loti. The asteroid's provisional name was 1929 NA.[2]
