cds-question@unistra.frmultiple-starssolar-system-planetsastrometryparallaxspectroscopyvisible-astronomyWide-band photometryproper-motionsstellar-spectral-typesUsing Hubble Space Telescope Fine Guidance Sensor astrometry and previously published radial velocity measures, we explore the exoplanetary system HD202206. Our modeling results in a parallax, {pi}_abs_=21.96+/-0.12 milliseconds of arc, a mass for HD202206B of M_B_=0.089_-0.006_^+0.007M_{Sun}_, and a mass for HD202206c of M_c_=17.9_-1.8_^+2.9^M_Jup_. HD202206 is a nearly face-on G + M binary orbited by a brown dwarf. The system architecture that we determine supports past assertions that stability requires a 5:1 mean motion resonance (we find a period ratio, P_c_/P_B_=4.92+/-0.04) and coplanarity (we find a mutual inclination, {Phi}=6{deg}+/-2{deg}).2017AJ....153..258Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/258CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2012)B/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2013)B/hst : HST Archived Exposures Catalog (STScI, 2007)I/322 : UCAC4 Catalogue (Zacharias+, 2012)I/317 : The PPMXL Catalog (Roeser+ 2010)I/305 : The Guide Star Catalog, Version 2.3.2 (GSC2.3) (STScI, 2006)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/254 : The HST Guide Star Catalog, Version 1.2 (Lasker+ 1996)J/AJ/152/141 : Solar neighborhood.
