Spin-Shape Model for 357 Ninnina
Abstract
We present a shape and spin axis model for main-belt asteroid 357 Ninina. The model was achieved with the lightcurve inversion process, using combined dense photometric data acquired from five apparitions between 2007-2023 and sparse data from USNO Flagstaff. Analysis of the resulting data found a sidereal period P = 35.9840 ± 0.0005 hours and two mirrored pole solutions at (l = 49°, b = 0°) and (λ = 230°, β = 36°) with an uncertainty of ± 10 degrees.
