Ornamenta was discovered by Auguste Charlois on 14 December 1892, in Nice, France. It was named in 1905 in honor of Antoinette Horneman, who was a member of the Société astronomique de France.[2]
During 2002, the asteroid was observed occulting a star. The resulting chords provided a diameter estimate of 99.5 km.[3]
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.[4]
