cds-question@unistra.frexoplanetsgravitational-lensinginfrared-photometryvisible-astronomyphotometryWe present the discovery of a planet on a very wide orbit in the microlensing event OGLE-2012-BLG-0838. The signal of the planet is well separated from the main peak of the event and the planet-star projected separation is found to be twice the Einstein ring radius, which corresponds to a projected separation of ~4au. Similar planets around low-mass stars are very hard to find using any technique other than microlensing. We discuss microlensing model fitting in detail and discuss the prospects for measuring the mass and distance of the lens system directly.2020AJ....159..261Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/261CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/337 : VISTA Variables in the Via Lactea Survey DR1 (Saito+, 2012)I/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/AcA/50/421 : OGLE-II DIA BUL_SC1 field (Wozniak, 2000)J/A+A/428/587 : Cepheids BVRIJHK dereddened magnitudes (Kervella+, 2004)J/A+A/533/A134 : Abundances microlensed stars in the Bulge (Bensby+, 2011)J/A+A/529/A75 : Limb-darkening coefficients (Claret+, 2011)J/other/Nat/481.167 : 2002-2007 PLANET microlensing events (Assan+, 2012)J/ApJ/814/92 : Spitzer IRAC events obs. in crowded fields (Calchi+,2015)J/MNRAS/449/2618 : M-dwarfs Multiples (MinMs) survey.
