2175 Andrea Doria, provisional designation 1977 TY, is a small, stony asteroid in the inner parts of the asteroid belt. It was discovered on October 12, 1977 by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland.[5] The S-type asteroid orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,205 days). It rotates around its axis with a period of 4.9 hours.[1]

Andrea Doria belongs to the Flora family of asteroids.[3] Although it is a small asteroid of just 4 kilometers in diameter, its surface is very reflective with a geometric albedo of almost 0.4, making it possible to be observed at an absolute magnitude of 13.8.[4]

It is named after the 16th-century Genoese admiral Andrea Doria, popularized in Friedrich Schiller's drama Fiesco.[2] Several ships, including the SS Andrea Doria, famous for its sinking off the coast of New England, had also been named after the admiral.
