Orbits of 47 Dwarf Satellite Galaxies of the Milky Way in Three Models
  of the Gravitational Potential with Different Masses
  The analysis of the orbits of 47 dwarf satellite galaxies of the Milky Way,
built using three models of the Galactic gravitational potential with different
masses, is presented. The models of the Galactic potential were chosen based on
the analysis of a large number of the Galaxy mass estimates known from the
literature. The astrometric data needed for calculation of the initial
positions and velocities (6D phase space) of the dwarf galaxies are also taken
from the literature, where the average proper motions were determined on the
basis of the data from the Gaia DR2 Catalog. We present the orbits and their
properties of all 47 dwarf galaxies obtained by integration for 13.5 Gyr
backward in all three models of the Galactic potential and give a comparison of
the orbital parameters. For each model of the Galactic potential we have
identified dwarf galaxies that are not connected gravitationally with the Milky
Way.
