The Potential Danger to Satellites due to Ejecta from a 2032 Lunar Impact by Asteroid 2024 YR4 [PDF]

Astrophysical Journal Letters
On 2032 December 22, the 60 m diameter asteroid 2024 YR _4 has a 4% chance of impacting the Moon. Such an impact would release 6.5 MT TNT equivalent energy and produce a ∼1 km diameter crater.

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

Monthly Notices of the Royal Astronomical Society, 2009
The triple asteroidal system (87) Sylvia is composed of a 280-km primary and two small moonlets named Romulus and Remus (Marchis et al. 2005b). Sylvia is located in the main asteroid belt, with semi-major axis of about 3.49 au, eccentricity of 0.08 and ...

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, spectral, and dynamical properties of asteroid (107) Camilla and its satellites [PDF]

Icarus, 2018
The population of large 100+ km asteroids is thought to be primordial. As such, they are the most direct witnesses of the early history of our Solar System available.

Orbits of very distant asteroid satellites

Astronomy & Astrophysics
Context. The very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very widely orbiting satellites and long orbital periods, on the order of tens to hundreds of days ...

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.

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 ...

Searching satellites of asteroid Itokawa by imaging observation with Hayabusa spacecraft [PDF]

, 2008
We carried out a search for satellites around Itokawa, the target asteroid of the Japanese Hayabusa mission. An imaging instrument, AMICA, on the spacecraft was used to take four images of Itokawa and its vicinity on September 1, 2005.

Irregular satellites of Jupiter: three-dimensional study of binary-asteroid captures [PDF]

, 2013
Among the hidden pieces of the giant puzzle, which is our Solar system, the origins of irregularsatellites of the giant planets stand to be explained, while the origins of regular satellites arewell explained by the in situ formation model through matter

Rapid formation of binary asteroid systems post rotational failure: A recipe for making atypically shaped satellites [PDF]

Icarus
Binary asteroid formation is a highly complex process, which has been highlighted with recent observations of satellites with unexpected shapes, such as the oblate Dimorphos by the NASA DART mission and the contact binary Selam by NASA\u27s Lucy mission.
