Observations with the adaptive optics system on the Very Large Telescope reveal that the outer main belt asteroid (702) Alauda has a small satellite with primary to secondary diameter ratio of ∼56. The secondary revolves around the primary in 4.9143 ± 0.007 days at a distance of 1227 ± 24 km, yielding a total system mass of (6.057 ± 0.36) × 1018 kg. Combined with an IRAS size measurement, our data yield a bulk density of 1570 ± 500 kg m−3 for this B-type asteroid. 

Binary asteroid (31) Euphrosyne: ice-rich and nearly spherical

Aims. Asteroid (31) Euphrosyne is one of the biggest objects in the asteroid main belt and it is also the largest member of its namesake family. The Euphrosyne family occupies a highly inclined

Asteroid masses obtained with INPOP planetary ephemerides

<p>We present here masses of 103 asteroids deduced from their perturbations on the<br />orbits of the inner planets, in particular Mars and the Earth. These determinations and the<br />INPOP19a

Families among high-inclination asteroids

A new method to determine the mean density of massive Solar System bodies

Mean densities of major and dwarf planets are possible to calculate by the values of the planets distance to the Sun, the mean densities of massive natural satellites of planets are computable by the

MASS DETERMINATION STUDIES OF 104 LARGE ASTEROIDS

The techniques described in an earlier paper were used to determine masses of 104 asteroids by the method of asteroid–asteroid gravitational interaction. For each of the 104 perturbers, 4 large sets

Mineralogical Criteria for the Parent Asteroid of the “Carbonaceous” Achondrite NWA 6704

The unique achondrite meteorite Northwest Africa (NWA) 6704 and its paired samples are fragments of an unknown parent asteroid that experienced large-scale igneous melting early in our solar system’s

Astrometric asteroid masses: a simultaneous determination

Using over 89 million astrometric observations of 349,737 numbered minor planets, an attempt was made to determine the masses of 230 of them by simultaneously solving for corrections to all orbital

Asteroid Family Associations of Active Asteroids

TLDR
A sequence of processes by which the formation of young asteroid families could lead to the production of present-day main-belt comets and disrupted asteroids is described.

Estimating the Porosity Structure of Granular Bodies Using the Lane–Emden Equation Applied to Laboratory Measurements of the Pressure–Density Relation of Fluffy Granular Samples

The porosity structure of a granular body is an important characteristic that affects evolutionary changes in the body. We conducted compression experiments using fluffy granular samples with various

A Low-Density M-type Asteroid in the Main Belt

TLDR
The orbital parameters of a satellite revolving around 22 Kalliope indicate that the bulk density of this main-belt asteroid is 2.37 ± 0.4 grams per cubic centimeter, indicating that Kalliopes cannot be predominantly composed of metal and may be composed of chondritic material with ∼30% porosity.

Binary Asteroids in the Near-Earth Object Population

TLDR
This system and other binary near-Earth asteroids have spheroidal primaries spinning near the breakup point for strengthless bodies, suggesting that the binaries formed by spin-up and fission, probably as a result of tidal disruption during close planetary encounters, may be binary systems.

ORBITS, MASSES, AND EVOLUTION OF MAIN BELT TRIPLE (87) SYLVIA

Sylvia is a triple asteroid system located in the main belt. We report new adaptive optics observations of this system that extend the baseline of existing astrometric observations to a decade. We

Radar Imaging of Binary Near-Earth Asteroid (66391) 1999 KW4

TLDR
High-resolution radar images reveal near-Earth asteroid (66391) 1999 KW4 to be a binary system that is dominated by an equatorial ridge at the object's potential-energy minimum and has exotic physical and dynamical properties.

IDENTIFICATION OF MAGNETITE IN B-TYPE ASTEROIDS

Spectrally blue (B-type) asteroids are rare, with the second discovered asteroid, Pallas, being the largest and most famous example. We conducted a focused, infrared spectroscopic survey of B-type

TLDR
This work reports on the mutual-orbit determination of 2001 QW322, a Kuiper Belt binary with a very large separation whose properties challenge binary-formation and -evolution theories.

The masses of the three largest asteroids: (1) Ceres, (2) Pallas and (4) Vesta were determined from gravitational perturbations exerted on respectively 25, 2, and 26 selected asteroids. These masses

Do asteroids have satellites

A substantial body of indirect evidence suggests that some asteroids have satellites, although none has been detected unambiguously. Collisions between asteroids provide physically plausible
