(3665) Fitzgerald is an asteroid of the main inner belt that was discovered on March 19, 1979 by the Czech astronomer Antonín Mrkos at the Kleť Observatory ( IAU code 046) near Český Krumlov . An unconfirmed sighting of the asteroid had already occurred on January 30, 1941 (1941 BL) at the observatory of the University of Turku .
The orbit of (3665) Fitzgerald around the Sun, like other 1500 known asteroids, has a 2: 1 resonance with that of the planet Mars . The largest of these asteroids are (4) Vesta , (44) Nysa and (142) Polana , which are named after groups of asteroids in this resonance zone. Of the 1500 asteroids, (3665) Fitzgerald's orbit is particularly synchronous with that of Mars.
The asteroid is named after the American jazz singer Ella Fitzgerald . It was named at the suggestion of the astronomers Miloš Tichý and Brian Marsden by the International Astronomical Union (IAU) on August 28, 1996. The lunar crater Fitzgerald, however, was named in 1970 after the Irish physicist George Francis FitzGerald .
