cds-question@unistra.frsurveysglobular-star-clustersgalaxiesastrometryThe goal of this paper is to demonstrate the outstanding quality of the second data release of the Gaia mission and its power for constraining many different aspects of the dynamics of the satellites of the Milky Way. We focus here on determining the proper motions of 75 Galactic globular clusters, nine dwarf spheroidal galaxies, one ultra-faint system, and the Large and Small Magellanic Clouds. Using data extracted from the Gaia archive, we derived the proper motions and parallaxes for these systems, as well as their uncertainties. We demonstrate that the errors, statistical and systematic, are relatively well understood. We integrated the orbits of these objects in three different Galactic potentials, and characterised their properties. We present the derived proper motions, space velocities, and characteristic orbital parameters in various tables to facilitate their use by the astronomical community. Our limited and straightforward analyses have allowed us for example to (i) determine absolute and very precise proper motions for globular clusters; (ii) detect clear rotation signatures in the proper motions of at least five globular clusters; (iii) show that the satellites of the Milky Way are all on high-inclination orbits, but that they do not share a single plane of motion; (iv) derive a lower limit for the mass of the Milky Way of 9.8^+6.7^_-2.7_x10^11^M_{sun}_ based on the assumption that the Leo~I dwarf spheroidal is bound; (v) derive a rotation curve for the Large Magellanic Cloud based solely on proper motions that is competitive with line-of-sight velocity curves, now using many orders of magnitude more sources; and (vi) unveil the dynamical effect of the bar on the motions of stars in the Large Magellanic Cloud. All these results highlight the incredible power of the Gaia astrometric mission, and in particular of its second data release.2018A&A...616A..12Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/616/A12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/616/A12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/616/A12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/616/A12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/616/A12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/616/A12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/616/A12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/616/A12/list (List of group (clusters, galaxies and ultra-faint system))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/616/A12/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/616/A12/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/616/A12/list?GETtext/xml+votable180.050000true80.8941667-69.75611110.005555555555555556Cone search capability for table J/A+A/616/A12/tabled3 (Possible members data for all groups)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/616/A12/tabled3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/616/A12/tabled3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/616/A12/tabled3?GETtext/xml+votable180.050000true81.0089550589526-76.98307513300930.0055555555555555563/517 520 4/2058-2059 2062 2065-2067 2084 2088-2089 2112 2344 3002 5/2584 2922 6801 7232 7854 8215 8221 8223 8227 8230-8231 8242 8257-8259 8288-8289 8292-8294 8304-8305 8344-8346 8360-8362 8364 8452 8456 8560 8887 8930 8970 8992 9346 9352 9354-9355 9384-9386 9616 9728 9730 10738 10806 11328-11329 11332-11333 11344-11345 11348 11965 11967 12002-12003 6/8744-8745 8747 9430 9433 9436-9438 9664 9666 10181-10183 10188-10189 10321 11692 11694 11861 12032-12034 12036 12405 12407 12943 14489 16645 16647 16656 16658 19091 21017 24843 25873 27212-27213 27215-27216 27218 27224 27574 27580 27975 27981 27984 27986 27992 28361 28705 28717 28741 28756-28757 28778 28799 28888-28889 28932-28933 28966-28967 28970 28972-28973 29184-29185 29187 29195 29216 29218-29219 29222 29231 29233 29248 29267 29288-29289 29291 29294 29315 29318 29377 29632 29636 29638 30376 30378 30769 30771 30995 30998 31018-31019 31043 31105 31113 31115 31410-31411 32855 32881 32883 32889 32903 32907 32914-32915 32918-32919 32962 32972 32974-32975 32980-32981 32983 33016 33018 33025-33027 33160-33161 33164-33165 33167 33180-33182 33224-33225 33228 33232-33234 33236 33360 33362 33388 33390 33452-33454 33460 33464 33472-33474 33480 33816 33828-33830 33832-33833 35199 35285 35287 35541 35543 35712 35714-35715 35744 35884 35886-35887 35972 35974 35976-35977 37291 37294 37390 37412 37414-37415 37548 37550 37633 37636 38123 38126 38468 38470 38916 38944 38946 39091 39094 39097 39099-39100 39102 39640 39642 41304-41305 41507 41510 41513 41522 41528 41847 41852 42070-42071 42073 42075-42078 42278 42314 42320 42336 42361 42700 42841 42956 42958 42976-42977 42980 42990-42991 43125 43219 43222 43228 43230 43248-43249 43252 44427 44430 45140-45141 45143 45320-45321 45324-45325 45336-45337 45340-45341 45384-45385 45396-45397 45759 45802 47125 47127 47168 47170 47755 47777 47839 47865 47970-47971 48026 48048 48050 48056 48058 48434 48440 48698 489521.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/616/A12?format=asciidefaultJ/A+A/616/A12/listList of group (clusters, galaxies and ultra-faint system)NameGroup namemeta.id.parentcharrecnoRecord number assigned by the VizieR team.
