Rubble pile asteroids

KJ Walsh - Annual Review of Astronomy and Astrophysics, 2018 - annualreviews.org
The moniker rubble pile is typically applied to all Solar System bodies> 200 m and<∼ 10 km
in diameter; in this size range, there is an abundance of evidence that nearly every object is …

Shapes, structures, and evolution of small bodies

Y Zhang, P Michel - Astrodynamics, 2021 - Springer
Small bodies are among the best tracers of our Solar System's history. A large number of
space missions to small bodies (past and future) offer a unique opportunity to use these …

The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation

JL Ortiz, P Santos-Sanz, B Sicardy, G Benedetti-Rossi… - Nature, 2017 - nature.com
Haumea—one of the four known trans-Neptunian dwarf planets—is a very elongated and
rapidly rotating body,,. In contrast to other dwarf planets,,, its size, shape, albedo and density …

Preliminary results from NEOWISE: an enhancement to the wide-field infrared survey explorer for solar system science

A Mainzer, J Bauer, T Grav, J Masiero… - The Astrophysical …, 2011 - iopscience.iop.org
ABSTRACT The Wide-field Infrared Survey Explorer (WISE) has surveyed the entire sky at
four infrared wavelengths with greatly improved sensitivity and spatial resolution compared …

Scaling forces to asteroid surfaces: The role of cohesion

DJ Scheeres, CM Hartzell, P Sánchez, M Swift - Icarus, 2010 - Elsevier
The scaling of physical forces to the extremely low ambient gravitational acceleration
regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found …

The strength of regolith and rubble pile asteroids

P Sánchez, DJ Scheeres - Meteoritics & Planetary Science, 2014 - Wiley Online Library
We explore the hypothesis that, due to small van der Waals forces between constituent
grains, small rubble pile asteroids have a small but nonzero cohesive strength. The nature of …

Binary asteroid population: 1. Angular momentum content

P Pravec, AW Harris - Icarus, 2007 - Elsevier
We compiled a list of estimated parameters of binary systems among asteroids from near-
Earth to trojan orbits. In this paper, we describe the construction of the list, and we present …

Spin limits of Solar System bodies: From the small fast-rotators to 2003 EL61

KA Holsapple - Icarus, 2007 - Elsevier
Holsapple [Holsapple, KA, 2001. Icarus 154, 432–448; Holsapple, KA, 2004. Icarus 172, 272–
303] determined the spin limits of bodies using a model for solid bodies without tensile or …

Rotational failure of rubble-pile bodies: influences of shear and cohesive strengths

Y Zhang, DC Richardson, OS Barnouin… - The Astrophysical …, 2018 - iopscience.iop.org
The shear and cohesive strengths of a rubble-pile asteroid could influence the critical spin at
which the body fails and its subsequent evolution. We present results using a soft-sphere …

Rotational fission of contact binary asteroids

DJ Scheeres - Icarus, 2007 - Elsevier
The energetics and dynamics of contact binary asteroids as they approach and pass the
rotational fission limit is studied. We presume that the asteroids are subject to an external …
