The physical and dynamical characteristics of the asteroid 4940 Polenov [PDF]
Serbian Astronomical Journal, 2021 The asteroid (1986 QY4) 4940 Polenov is the first Solar system object whose 3D shape is determined using the observations from the newly built Astronomical Station Vidojevica (ASV).

On the rotation of cometary nuclei and small asteroids [PDF]
International Astronomical Union Colloquium, 1985 AbstractThe spin rate distributions of comet nuclei and small asteroids are compared, and it is shown that Whipple’s (1982) finding of a faster average rotation for the asteroid sample was due to observational biases. In fact, the presently available rotational data do not exhibit any clear differentiation among comet nuclei and asteroids, except ...

Preliminary refinement of rotation parameters of asteroids based on photogrammetric processing of on-orbit remote sensing images [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesIn recent years, asteroid exploration has become an important research direction in the field of deep space exploration. The weak gravitational environment of asteroids, as well as their complex topographic, geomorphic, and dynamic characteristics, pose ...

The Alinement of Asteroid Rotation [PDF]
International Astronomical Union Colloquium, 1971 Data have been accumulating since the beginning of this century that indicate that most, if not all, large asteroids have periodic lightcurves. The variations that are seen have periods of the order of several hours and can be understood as being caused by bodily rotation, accompanied by changes in shape and/or surface properties. Because corresponding

Asteroid Photometric Phase Functions From Bayesian Lightcurve Inversion
Frontiers in Astronomy and Space Sciences, 2022 Photometry is an important tool for characterizing the physical properties of asteroids. An asteroid’s photometric lightcurve and phase curve refer to the variation of the asteroid’s disk-integrated brightness in time and in phase angle (the Sun-asteroid-

Collisional and Rotational Disruption of Asteroids [PDF]
Advanced Science Letters, 2011 Asteroids are leftover pieces from the era of planet formation that help us understand conditions in the early Solar System. Unlike larger planetary bodies that were subject to global thermal modification during and subsequent to their formation, these small bodies have kept at least some unmodified primordial material from the solar nebula.
