On the stability of the satellites of asteroid 87 Sylvia [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2009
he triple asteroidal system (87) Sylvia is composed of a 280-km primary and two small moonlets named Romulus and Remus (Marchis et al 2005). Sylvia is located in the main asteroid belt. The satellites are in nearly equatorial circular orbits around the primary.

Lunar ejecta origin of near-Earth asteroid Kamo’oalewa is compatible with rare orbital pathways [PDF]

open access: yesCommunications Earth & Environment, 2023
Near-Earth asteroid, Kamo’oalewa (469219), is one of a small number of known quasi-satellites of Earth; it transitions between quasi-satellite and horseshoe orbital states on centennial timescales, maintaining this dynamics over megayears. The similarity

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

open access: hybridNature
AbstractAsteroids 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 evolution2. (152830) Dinkinesh is a small asteroid orbiting the Sun near the inner edge of the main asteroid belt ...

EFFECT OF NON-SPHERICITY OF GRAVITATIONAL FIELD OF THE ASTEROID ON THE ITS SATELLITES ORBITS EVOLUTION

open access: diamondOdessa Astronomical Publications, 2016
Lately it has become possible to sufficiently precise definition of the physical and geometric characteristics of asteroid systems using radar observations (http://echo.jpl.nasa.gov/~lance/binary.neas.html), which allowed calculating the asymmetry of the

Multisatellite Task Allocation and Orbit Planning for Asteroid Terminal Defence

open access: yesAerospace, 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.

Feasibility Analysis of Autonomous Orbit Determination and Gravity-Field Recovery around Asteroids Using Inter-Satellite Range Data [PDF]

open access: goldAerospace, 2023
Autonomous navigation and orbit determination are key problems of asteroid exploration missions. Inter-satellite range link is a type of measurement widely used in the orbit determination of Earth satellites, but not so widely used in missions around ...

Inflatable Dome for Moon, Mars, Asteroids and Satellites

open access: greenAIAA SPACE 2007 Conference & Exposition, 2007
On a planet without atmosphere, sustaining human life is very difficult and dangerous, especially during short sunlit period when low temperature prevails. To counter these environmental stresses, the author offer an innovative artificial "Evergreen" dome, an inflated hemisphere with interiors continuously providing a climate like that of Florida ...

Direct N-body Simulations of Satellite Formation around Small Asteroids: Insights from DART’s Encounter with the Didymos System [PDF]

open access: goldThe Planetary Science Journal
We explore binary asteroid formation by spin-up and rotational disruption considering the NASA DART mission's encounter with the Didymos–Dimorphos binary, which was the first small binary visited by a spacecraft.

Trojan Asteroid Satellites, Rings, and Activity [PDF]

open access: hybridSpace Science Reviews, 2023
The 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 ...
