480 Hansa is a minor planet orbiting the Sun.

This object is the namesake of the Hansa family^[2] of 162–839 asteroids that share similar spectral properties and orbital elements. Hence they may have arisen from the same collisional event. All members have a relatively high orbital inclination.^[3]
