Ornamenta was discovered by Auguste Charlois on December 14, 1892, in Nice, France. It was named in 1905 after Antoinette Horneman, who was a member of the Société astronomique de France.[2]

This object is the namesake of a family of 14–93 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]
