Determinations of Asteroid Masses Using Mutual Encounters Observed in the Legacy Survey of Space and Time

The Planetary Science Journal
Using published simulations of the 10 yr Legacy Survey of Space and Time (LSST), we forecast its ability to determine the masses of individual main-belt asteroids (MBAs) through precise astrometry of any pairs of the ≈1.2 million known MBAs undergoing ...

Revised Ephemerides of the Martian Satellites, Phobos and Deimos

The Astronomical Journal
We report on the new ephemerides (MAR099) for the satellites of Mars derived from a large set of ground-based and spacecraft astrometric measurements. Our integrated orbit fit yielded latest estimates for the Martian tidal parameter τ = k _2 / Q = 1.816 ±
