Abstract Asteroid Justitia is a special main-belt object, being an extremely red body with steeper spectral slope than any other D-type asteroid. Conversely, its and polarimetric properties resemble organics-rich Centaurs trans-Neptunian objects. For this reason, it was chosen as main target of the MBR Explorer space mission. It crucial for mission planning operations to have in advance best estimate size, spin, shape, surface. In particular, size determination high demand before extensive...
As evidenced by recent survey results, majority of asteroids are slow rotators (P>12 h), but lack spin and shape models due to selection bias. This bias is skewing our overall understanding the spins, shapes, sizes asteroids, as well their other properties. Also, diameter determinations for large (>60km) medium-sized (between 30 60 km) often vary over 30% multiple reasons. Our long-term project focused on a few tens with periods up hours. We aim obtain full light curves reconstruct...
Introduction:Determining the physical parameters of asteroids is a complex yet crucialtask in planetary science. Recent advancements observational techniques andthe availability vast data have led to development numerous analyticaland modelling approaches for parameter determination.In our research, we focused on studying several main-belt usinghigh-quality data. Initially, modelled visible lightcurves using convex inver-sion (see [1] and [2]) obtaining precise information spin axis an...
ContextAsteroid (269) Justitia is a main-belt asteroid with unusual surface properties. Its reflectance spectrum extremely red, unlike any other taxonomic type found in the main belt, and not even within Jupiter Trojan population (Hasegawa et al. 2021). However, such closely resembles spectra of trans-Neptunian Objects. Also polarimetric properties are (Gil-Hutton & García-Migani 2017), both very small depth negative polarisation branch also angle minimum polarisation. These...
