2175 Andrea Doria, provisional designation 1977 TY, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter.

It was discovered on 12 October 1977, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, and named after 16th-century Genoese admiral Andrea Doria.[2][8]

Orbit and classification

Andrea Doria is a member of the Flora family, one of the largest families of stony asteroids in the main belt. It orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,205 days). Its orbit has an eccentricity of 0.21 and an inclination of 4° with respect to the ecliptic.[1] A first precovery was taken at Palomar Observatory in 1950, extending the body's observation arc by 27 years prior to its official discovery observation at Zimmerwald.[8]
