Ninina ( minor planet designation: 357 Ninina) is a large main-belt asteroid. [1] It was discovered by Auguste Charlois on February 11, 1893, in Nice. The reference of its name is not known, though Ninine is a French personal name. [2] This minor planet is orbiting at a distance of 3.16 AU from the Sun with a period of 5.61 years and an orbital eccentricity (ovalness) of 0.074. The orbital plane is inclined at an angle of 15.1° to the plane of the ecliptic. [1]
Photometric observations of 357 Ninina during 2023 provided a light curve that presents an Earth commensurate rotation period of 36.00±0.01 h with a brightness amplitude of 0.08±0.01 in magnitude. [3] In 2024, spin shape modelling using the light curve inversion technique show a blocky, rounded figure, with a refined rotation period of 35.9840±0.0005 h [4]
