193 Ambrosia is a main belt asteroid that was discovered by the French (Corsican) astronomer J. Coggia on February 28, 1879 and named after Ambrosia, the food of the gods in Greek mythology.
In 2009, Photometric observations of this asteroid were made at the Palmer Divide Observatory in Colorado Springs, Colorado. The resulting light curve shows a synodic rotation period of 6.580 ± 0.001 hours with a brightness variation of 0.11 ± 0.02 in magnitude. This result is consistent with an independent study performed in 1996.[2]
