30 Urania is a large main-belt asteroid that was discovered by English astronomer John Russell Hind on July 22, 1854.<ref name="IAU_MPC"/> It was his last asteroid discovery. This object is named after Urania, the Greek Muse of astronomy. Initial orbital elements for 30 Urania were published by Wilhelm Günther, an assistant at Breslau Observatory.<ref name="Gunther1855"/> It is orbiting the Sun with a period of Template:Convert and is spinning on its axis once every 13.7 hours.

Based upon its spectrum, this is classified as a stony S-type asteroid.<ref name="DeMeo2009"/> During 2000, speckle interferometry measurements from the Telescopio Nazionale Galileo in the Canary Islands were used to measure the apparent size and shape of 30 Urania. This gave cross-sectional dimensions equivalent to an ellipse with a length of 111 km and a width of 89 km, for a ratio of 0.80.<ref name="Cellino2003"/>

The astrological symbol for Urania is , compass calipers.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
