74503 Madola, provisional designation ', is a background asteroid from the outer region of the asteroid belt, approximately 4.5 kilometers in diameter. It was discovered on 23 February 1999, by Canadian astronomer Denis Bergeron at the Val-des-Bois Observatory in Quebec, Canada. The asteroid was named for the three Canadian astronomers Christian Marois, René Doyon and David Lafrenière. Orbit and classification ''Madola'' is a non-family from the main belt's background population. It orbits the Sun in the outer asteroid belt at a distance of 2.5–3.6 AU once every 5 years and 3 months (1,912 days; semi-major axis of 3.02 AU). Its orbit has an eccentricity of 0.18 and an inclination of 17 ° with respect to the ecliptic. The body's observation arc begins with a precovery taken by Spacewatch in April 1994, almost 6 years prior to its official discovery observation at Val-des-Bois.
