Until very recently, the mass of minor planet 2 Pallas had been determined
from its gravitational effects on only 1 Ceres and the planet Mars. An independent
confirmation was therefore highly desirable. This paper presents individual mass
determinations based on close encounters with 16 other minor planets, as well
as a simultaneous solution using all objects. The resulting value for the mass
of Pallas, 
, essentially confirms
the result from Ceres alone.
Key words: astrometry / minor planets, asteroids / planets and satellites: individual: 2 Pallas
