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":"wasp-14-b","name":"WASP-14 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":528.3635472097928,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":218.2766247,"dec_deg":21.8946875,"epoch_ra_deg":218.584244,"epoch_dec_deg":21.776129,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-14","semi_major_axis_km":5535121.215899999,"periapsis_km":null,"mass_kg":1.6779505562633987e+28,"mass_msun":0.00843866,"constellation":"Boötes","discovered":"2008","featured":false,"url":"https://spacecatalog.org/object/wasp-14-b","radius_km":98659.129602,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-14","host_v_mag":9.745,"eccentricity":0.09,"uncertainties":{"mass_kg":[2.657387758788188e+27,2.657387758788188e+27],"radius_km":[5719.369832,5719.369832],"distance_ly":[2.6157741492882822,2.641866659505622],"host_mass_solar":[0.39,0.39],"inclination_deg":[0.62,0.62],"host_radius_solar":[0.08,0.08],"host_temperature_k":[100,100],"semi_major_axis_km":[149597.8707,149597.8707],"orbital_period_days":[0.00001,0.00001],"argument_of_periastron_deg":[0.41,0.41]},"host_mass_solar":1.62,"inclination_deg":84.32,"stars_in_system":3,"discovery_method":"Transit","host_radius_solar":1.4,"planets_in_system":1,"discovery_facility":"SuperWASP","host_temperature_k":6475,"orbital_period_days":2.24375,"transit_midpoint_bjd":2455643.79792,"equilibrium_temperature_k":1872,"argument_of_periastron_deg":251.61},"designations":[{"catalog":"Exoplanet","designation":"WASP-14 b"},{"catalog":"Host star","designation":"WASP-14"}],"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.
