The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"ogle-tr-211-b","name":"OGLE-TR-211 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":4942.117128990726,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":160.0598236,"dec_deg":-62.4555353,"epoch_ra_deg":160.30225,"epoch_dec_deg":-62.595393,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"OGLE-TR-211","semi_major_axis_km":7629491.405699999,"periapsis_km":null,"mass_kg":1.9549951236893757e+27,"mass_msun":0.000983195,"constellation":"Carina","discovered":"2007","featured":false,"url":"https://spacecatalog.org/object/ogle-tr-211-b","radius_km":97227.7564,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"OGLE-TR-211","host_v_mag":15.364,"eccentricity":0,"uncertainties":{"mass_kg":[3.796089061804235e+26,3.796089061804235e+26],"radius_km":[6435.5028999999995,12871.005799999999],"distance_ly":[358.20124182741347,358.20124182741347],"host_mass_solar":[0.05,0.05],"host_radius_solar":[0.07,0.21],"host_temperature_k":[91,91],"semi_major_axis_km":[149597.8707,149597.8707],"orbital_period_days":[0.00003,0.00003]},"host_mass_solar":1.33,"inclination_deg":87.2,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.64,"planets_in_system":1,"discovery_facility":"OGLE","host_temperature_k":6325,"orbital_period_days":3.67724,"transit_midpoint_bjd":2453428.334,"equilibrium_temperature_k":1686},"designations":[{"catalog":"Exoplanet","designation":"OGLE-TR-211 b"},{"catalog":"Host star","designation":"OGLE-TR-211"}],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
