Gismonda ( minor planet designation: 492 Gismonda) is a main belt asteroid discovered by German astronomer Max Wolf in 1902. Gismonda is named after the daughter of Tancred, prince of Salerno, from Giovanni Boccaccio's work, The Decameron. [2] It is orbiting 3.11 AU (466 Gm) from the Sun with a period of 5.49 yr and an orbital eccentricity (ovalness) of 0.18. The orbital plane is inclined at an angle of 1.6° to the plane of the ecliptic. [1]
This asteroid is a member of the Themis collisional family, which is one of the largest such groups in the belt. It has an estimated diameter of 50.3±1.1 km. The spectrum suggests the surface is covered with a fine grained silicate mantle. [3] Photometric observations of Gismonda made in 1902 produce a light curve displaying a rotation period of 6.488±0.005 h with a brightness variation of 0.16±0.02 in magnitude [4]
