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":"kepler-682-b","name":"Kepler-682 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":6455.450105958644,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":289.1122204,"dec_deg":51.7373589,"epoch_ra_deg":289.276113,"epoch_dec_deg":51.784308,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-682","semi_major_axis_km":15827454.72006,"periapsis_km":null,"mass_kg":2.5441435116791275e+26,"mass_msun":0.000127949,"constellation":"Cygnus","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kepler-682-b","radius_km":47006.597,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-682","host_v_mag":15.556,"eccentricity":0,"uncertainties":{"radius_km":[3189.05,4911.137000000001],"distance_ly":[309.84855883090626,341.9749620360055],"host_mass_solar":[0.052,0.043],"host_radius_solar":[0.059,0.093],"host_temperature_k":[82.16,84.63],"orbital_period_days":[0.000006463,0.000006463]},"host_mass_solar":0.92,"inclination_deg":88.17,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.89,"planets_in_system":1,"discovery_facility":"Kepler","host_temperature_k":5559,"orbital_period_days":12.611906672,"transit_midpoint_bjd":2455013.892444,"equilibrium_temperature_k":753},"designations":[{"catalog":"Exoplanet","designation":"Kepler-682 b"},{"catalog":"Host star","designation":"Kepler-682"}],"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":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
