INVESTIGATION OF NEO ASTEROIDS 2006 VB14 AND 1986 DA

Odessa Astronomical Publications, 2019
566 positions and photometric observa- tions of NEO objects 2006 VB14 = Y5705 = 345705 and 1986 DA were obtained with Baldone Schmidt telescope in 2018 and 2019, to detecting rotation period and other physical characteristics.

YORP and Yarkovsky effects in asteroids (1685) Toro, (2100) Ra-Shalom, (3103) Eger, and (161989) Cacus

, 2017
The rotation states of small asteroids are affected by a net torque arising from an anisotropic sunlight reflection and thermal radiation from the asteroids' surfaces. On long timescales, this so-called YORP effect can change asteroid spin directions and

Stability of a Rotating Asteroid Housing a Space Station

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.

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.

Dynamic autonomous intelligent control of an asteroid lander [PDF]

, 2010
One of the future flagship missions of the European Space Agency (ESA) is the asteroid sample return mission Marco-Polo. Although there have been a number of past missions to asteroids, a sample has never been successfully returned.

The binary near-Earth asteroid (175706) 1996 FG3 - An observational constraint on its orbital evolution [PDF]

, 2014
Using our photometric observations taken between 1996 and 2013 and other published data, we derived properties of the binary near-Earth asteroid (175706) 1996 FG3 including new measurements constraining evolution of the mutual orbit with potential ...

An Efficient Numerical Approach to Modeling the Effects of Particle Shape on Rubble-pile Dynamics

The Planetary Science Journal, 2023
We present an approach for the inclusion of nonspherical constituents in high-resolution N -body discrete element method (DEM) simulations. We use aggregates composed of bonded spheres to model nonspherical components.

Near-Earth asteroid (3200) Phaethon. Characterization of its orbit, spin state, and thermophysical parameters

, 2016
The near-Earth asteroid (3200) Phaethon is an intriguing object: its perihelion is at only 0.14 au and is associated with the Geminid meteor stream.

Parking a Spacecraft near an Asteroid Pair [PDF]

, 2005
This paper studies the dynamics of a spacecraft moving in the field of a binary asteroid. The asteroid pair is modeled as a rigid body and a sphere moving in a plane, while the spacecraft moves in space under the influence of the gravitational field of
