193 Ambrosia (Symbol: 
) is a main belt asteroid that was discovered by the Corsican-born French astronomer J. Coggia on February 28, 1879, and named after either Ambrosia, the food of the gods in Greek mythology, or Ambrosia, one of the Hyades. Lutz D. Schmadel argued that the second possibility was more likely, based on the fact that Coggia named another asteroid, 217 Eudora, after another of the Hyades. [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]
