Satellite Formation around the Largest Asteroids

The Astrophysical Journal Letters
Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13 asteroids larger than 100 km are known to have satellites, but none have ...

Celestial Bodies Far-Range Detection with Deep-Space CubeSats [PDF]

Sensors, 2023
Detecting celestial bodies while in deep-space travel is a critical task for the correct execution of space missions. Major bodies such as planets are bright and therefore easy to observe, while small bodies can be faint and therefore difficult to ...

A contact binary satellite of the asteroid (152830) Dinkinesh. [PDF]

Nature
Abstract Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques (that is, YORP, short for the Yarkovsky–O’Keefe–Radzievskii–Paddack effect) 1 to be a notable factor in their evolution 2

Multisatellite Task Allocation and Orbit Planning for Asteroid Terminal Defence

Aerospace, 2022
Near-Earth asteroids are a great threat to the Earth, especially potential rendezvous and collision asteroids. To protect the Earth from an asteroid collision, it is necessary to investigate the asteroid defence problem.

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.

Design and ballistic analysis of the mission for long-term study of the asteroid Apophis by a nanosatellite with an electric rocket propulsion system

Космические аппараты и технологии, 2020
The paper considers non-spherical objects with low gravitational attraction, such as asteroids, satellites of the planet and comets. We considered possibility of a mission to small bodies of the solar system of irregular shape on the example of the ...

Trojan Asteroid Satellites, Rings, and Activity

Space Science Reviews, 2023
AbstractThe Lucy mission will encounter five Jupiter Trojans during its mission with three of the five already known to be multiple systems. These include a near-equal-mass binary, a small and widely separated satellite, and one intermediate-size satellite system.

THE PRECESSION OF ASTEROID 1620 GEOGRAPHOS

Odessa Astronomical Publications, 2017
The frequency analysis of the fine photometric effects in the photometric observation obtained during asteroid 1620 Geographos approaching to Earth in 1994 allowed to derive the precession of asteroid spin axis.
