Stability of a Rotating Asteroid Housing a Space Station [PDF]
Frontiers in Astronomy and Space Sciences, 2019 Today there are numerous studies on asteroid mining. They elaborate on selecting the right objects, prospecting missions, potential asteroid redirection, and the mining process itself.

On the dynamics of non-rigid asteroid rotation [PDF]
Acta Astronautica 161, August 2019, 2019 We have presented in this communication a new solving procedure for the dynamics of non-rigid asteroid rotation, considering the final spin state of rotation for a small celestial body (asteroid). The last condition means the ultimate absence of the applied external torques (including short-term effect from torques during collisions, long-term YORP ...

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.

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).

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.

Deficit of primitive compositions in binary asteroids and pairs [PDF]
A&A 672, A48 (2023), 2023 Context. Small binary asteroid systems and pairs are thought to form through fission induced by spin up via the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect. This process is expected to depend on their structural strength, hence composition. Aims.

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 ...

Reconstruction of asteroid spin states from Gaia DR3 photometry [PDF]
A&A 675, A24 (2023), 2023 Gaia Data Release 3 contains accurate photometric observations of more than 150,000 asteroids covering a time interval of 34 months. With a total of about 3,000,000 measurements, a typical number of observations per asteroid ranges from a few to several tens. We aimed to reconstruct the spin states and shapes of asteroids from this dataset. We computed

On the secondary’s rotation in a synchronous binary asteroid [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT This article studies the secondary’s rotation in a synchronous binary asteroid system in which the secondary enters the 1:1 spin-orbit resonance. The model used is the planar full two-body problem, composed of a spherical primary plus a triaxial ellipsoid secondary.
