(12) Victoria is an asteroid of the main asteroid belt discovered by John Russell Hind as the twelfth asteroid on September 13, 1850 .

The naming was controversial at the time because it was generally believed that Hind named the celestial body in honor of the British Queen Victoria - until then it was unusual to name asteroids after living people. Hind pointed out, however, that the Roman goddess of victory was the namesake. The name Klio was also given, which was later given (1865) for the asteroid (84) Klio . "A star with a laurel branch" was suggested as a symbol.

Victoria moves to a distance of 1.8191 ( perihelion ) to 2.8495 ( aphelion ) astronomical units , in 3.57 years around the sun . The orbit is 8.3619 ° inclined to the ecliptic , the orbit eccentricity is 0.2207.

Victoria has a mean diameter of 113 kilometers. The asteroid has a relatively bright surface with an albedo of 0.176. It rotates around its own axis in around 8 hours and 40 minutes.

Recordings made using radar and speckle interferometry show that the asteroid is elongated in shape. It may consist of two bodies.
