193 Ambrosia is a main belt asteroid that was discovered by the Corsican-born French astronomer J. Coggia on February 28, 1879, and named after Ambrosia, the food of the gods in Greek mythology.[4]
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.[3]
