Density of asteroids

Benoit Carry
- 01 Dec 2012 - 
- Vol. 73, Iss: 1, pp 98-118
TLDR
DeMeo et al. as mentioned in this paper presented a review of the current knowledge of the density of small bodies and compared with meteorite density, allowing to estimate the macroporosity (i.e., amount of voids) within these bodies.

Gaia Data Release 2. Observations of solar system objects

Federica Spoto, +501 more
TL;DR: In this paper, the authors describe the processing of the Gaia DR2 data, and describe the criteria used to select the sample published in Gaia DR 2, and explore the data set to assess its quality.

Solar System evolution from compositional mapping of the asteroid belt

TL;DR: The asteroids in the main asteroid belt have been discovered to be more compositionally diverse with size and distance from the Sun than had previously been known, implying substantial mixing through processes such as planetary migration and the subsequent dynamical processes.
Journal ArticleDOI

The taxonomic distribution of asteroids from multi-filter all-sky photometric surveys

TL;DR: In this article, the authors presented a method to bias-correct the asteroid population observed in the Sloan Digital Sky Survey (SDSS) according to size, distance, and albedo.

Localized sources of water vapour on the dwarf planet (1) Ceres

TL;DR: In this article, the infrared spectra obtained by ESA's Herschel Space Observatory provide unambiguous evidence that there is water ice at or near the surface of Ceres, and water vapour is issuing at a rate of at least 1026 molecules per second from sources localized to mid-latitude regions.

Origin of the orbital architecture of the giant planets of the Solar System.

TL;DR: This model reproduces all the important characteristics of the giant planets' orbits, namely their final semimajor axes, eccentricities and mutual inclinations, provided that Jupiter and Saturn crossed their 1:2 orbital resonance.

A low mass for Mars from Jupiter's early gas―driven migration

TL;DR: Simulation of the early Solar System shows how the inward migration of Jupiter to 1.5 au, and its subsequent outward migration, lead to a planetesimal disk truncated at 1’au; the terrestrial planets then form from this disk over the next 30–50 million years, with an Earth/Mars mass ratio consistent with observations.
Journal ArticleDOI

Chaotic capture of Jupiter's Trojan asteroids in the early Solar System.

TL;DR: It is shown that the Trojans could have formed in more distant regions and been subsequently captured into co-orbital motion with Jupiter during the time when the giant planets migrated by removing neighbouring planetesimals.

An extension of the Bus asteroid taxonomy into the near-infrared

TL;DR: An asteroid taxonomy classification system based on reflectance spectrum characteristics for 371 asteroids measured over the wavelength range 0.45 to 2.45 μm is presented and nearly all of the Bus taxonomy classes are preserved, with one new class (Sv).
