The rotation period is one of the fundamental physical characteristics of asteroids. It can be determined from photometric measurements by standard methods of time-series period analysis or by creating a physical model of an asteroid with the rotatio

In our study, we used the convex inversion thermophysical models (CITPM) by Durech et al. [1] to constrain asteroid's shape model and parameters, including thermal inertia, geometric albedo, and surface roughness simultaneously from optical and infra

The origin of Jupiter Trojans (JTs) remains an open problem. The currently leading theory assumes that JTs were captured to their orbits near the Lagrangian points during the early reconfiguration of the giant planets (Morbidelli et al. 2005; Nesvorn

(99942) Apophis is a near-Earth asteroid that will closely approach to Earth in 2029; the minimum geocentric distance will be about 38,000 km. During the approach, the spin state of Apophis is expected to be altered by Earth's gravitation torque. The

Space weathering is a process that changes the surface of airless planetary bodies. Prime space weathering agents are solar wind irradiation and micrometeoroid bombardment. These processes alter planetary reflectance spectra and often modify their co
