1127 Mimi is a main belt asteroid orbiting the Sun. Approximately 46 kilometers in diameter, it makes a revolution around the Sun once every 4 years. It completes one rotation once every 13 hours. It was discovered by Sylvain Julien Victor Arend on January 13, 1929. It was named for the wife of astronomer Eugène Joseph Delporte. Through an error, the names intended for 1127 Mimi and 1145 Robelmonte had been switched, and each name had been proposed by the discoverer of the other asteroid. Its provisional designation was 1929 AJ.
