AbstractWe propose to the NSFA (the IAU Working Group on Numerical Standards for Fundamental Astronomy) the following representative values and realistic uncertainties for the masses of the three largest asteroids (Ceres, Pallas, Vesta), to be used as the current best estimates: $$\begin{array}{ll}M_{\rm Ceres}/M_\odot \,=\, 4.72(3)\cdot 10^{-10},\\ M_{\rm Pallas}/M_\odot \,=\, 1.03(3)\cdot 10^{-10},\\ M_{\rm Vesta}/M_\odot\, =\, 1.35(3)\cdot 10^{-10}.\end{array}$$Unlike the values previously… 
Values of some astronomical constants proposed for NSFA
Improved values for the masses of Ceres, Pallas, Vesta, the Earth-Moon mass ratio, and the Astronomical Unit are hereby proposed to the NSFA WG (the IAU Working Group on Numerical Standards for
Relativistic effects and dark matter in the Solar system from observations of planets and spacecraft
The high precision of the latest version of the planetary ephemeris EPM2011 enables one to explore more accurately a variety of small effects in the solar system. The processing of about 678 thousand

The inclination I of an Earth’s satellite in polar orbit undergoes a secular De Sitter precession of $$-\,7.6$$-7.6 milliarcseconds per year for a suitable choice of the initial value of its
The Araucaria Project: High-precision orbital parallax and masses of the eclipsing binary TZ~Fornacis
Context: Independent distance estimates are particularly useful to check the precision of other distance indicators, while accurate and precise masses are necessary to constrain evolution models.
Changes in the Sun’s mass and gravitational constant estimated using modern observations of planets and spacecraft
More than 635 thousand positional observations of planets and spacecraft of various types (mostly radiotechnical ones, 1961–2010) were used to estimate possible changes in the gravitational constant,
Constraints on dark matter in the solar system
We have searched for and estimated the possible gravitational influence of dark matter in the Solar system based on the EPM2011 planetary ephemerides using about 677 thousand positional observations

Increase of the mean Sun–Earth distance caused by a secular mass accumulation
Based on many planetary observations between the years 1971 and 2003, Krasinsky and Brumberg (Celest. Mech. Dyn. Astron. 90:267–288, 2004) have estimated a rate of increase in the mean Sun-Earth
Effects of standard and modified gravity on interplanetary ranges
We numerically investigate the impact on the two-body range of several Newtonian and non-Newtonian dynamical effects for some Earth-planet (Mercury, Venus, Mars, Jupiter, Saturn) pairs, in view of


Astrometric masses of 21 asteroids, and an integrated asteroid ephemeris
We apply the technique of astrometric mass determination to measure the masses of 21 main-belt asteroids; the masses of 9 Metis (1.03 ± 0.24 × 10-11 M⊙), 17 Thetis (6.17 ± 0.64 × 10-13 M⊙), 19
Determination of asteroid masses --- I. (1) Ceres, (2) Pallas and (4) Vesta
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
US Naval Observatory Ephemerides of the Largest Asteroids
A new set of ephemerides for 15 of the largest asteroids has been produced for use in the Astronomical Almanac. The ephemerides cover the period from 1800 through 2100. The internal uncertainty in

The Astronomical Unit is one of the most basic units of astronomy: the scale of the solar system. Yet its long and colorful history is sprinkled liberally with incorrect descriptions and mis-quoted
The mass of (1) Ceres from its gravitational perturbations on the orbits of 9 asteroids
The mass of (1) Ceres is about half of the total mass of the main asteroid belt, and its long-term perturbations on the orbits of many solar system objects are important. For this rea- son, a very

New masses of eight asteroids: (6) Hebe, (10) Hygiea, (15) Eunomia, (52) Europa, (88) Thisbe, (444) Gyptis, (511) Davida, and (704) Interamnia, were determined. In most cases, the masses were
