(13116) Hortensia Main-belt Asteroid
Discovered on 9 October 1993 by E. W. Elst at La Silla.
Hortensia is the name of a flower (Hydrangea hortensia) introduced to France by the astronomer Le Gentil on his return from observing the transits of Venus in India. Although he originally proposed to name this flower Pautia, either name would honor the orbit computer Nicole-Reine Lepaute, née Étable de la Brière.Naming citation (WGSBN Bull. 3, #12, 7), IAU / Minor Planet Center, via NASA/JPL
