Mathematics, 2023 We have considered here a novel particular model for dynamics of a non-rigid asteroid rotation, assuming the added mass model instead of the concept of Viscoelastic Oblate Rotators to describe the physically reasonable response of a ‘rubble pile ...

Physical Properties of the Young Asteroid Pair 2010 UM26 and 2010 RN221
The Astronomical Journal, 2023 The main belt asteroids 458271 (2010 UM26) and 2010 RN221 share almost identical orbital elements, and currently appear as comoving objects ∼30″ apart in the plane of the sky.

Frontiers in Astronomy and Space Sciences, 2022 The authors explore the possibility that near-earth, rubble pile asteroids might be used as habitats for human settlement by increasing their rotation to produce spin gravity. Using previously published scaling by Maindl et al.

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).

Asteroid Deflection by Leveraging Rotational Self-Energy [PDF]
Journal of Spacecraft and Rockets, 2021 A novel concept for the deflection of rotating asteroids is presented, based on the conversion of the asteroid rotational kinetic energy into translational kinetic energy. Such conversion is achieved using an orbital siphon, a tether-connected chain of masses, arranged vertically from the asteroid surface, which exploits the rotation of the asteroid ...

Thermophysical Investigation of Asteroid Surfaces. II. Factors Influencing Grain Size
The Planetary Science Journal, 2022 Asteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms—impact bombardment and thermal fatigue—have been proposed as viable and dominant weathering processes ...

ROTATIONAL PROPERTIES OF THE MARIA ASTEROID FAMILY [PDF]
The Astronomical Journal, 2014 Maria family is regarded as an old-type (~3 +/- 1 Gyr) asteroid family which has experienced substantial collisional and dynamical evolution in the Main-belt. It is located nearby the 3:1 Jupter mean motion resonance area that supplies Near-Earth asteroids (NEAs) to the inner Solar System.

Dynamics of asteroid systems post-rotational fission
Astronomy & Astrophysics, 2022 Asteroid binaries found among the near-Earth objects are believed to have formed from rotational fission. In this paper, we study the dynamical evolution of asteroid systems the moment after fission. The model considers two bodies the moment after a contact binary separates due to rotational fission.
