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-93-b","name":"WASP-93 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1207.7048816646661,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":9.4587443,"dec_deg":51.288778,"epoch_ra_deg":9.831512,"epoch_dec_deg":51.436628,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-93","semi_major_axis_km":6299566.335177,"periapsis_km":null,"mass_kg":2.790257146727597e+27,"mass_msun":0.00140326,"constellation":"Cassiopeia","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/wasp-93-b","radius_km":114172.92027130001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-93","host_v_mag":10.966,"eccentricity":0,"uncertainties":{"mass_kg":[5.504588928918389e+26,5.504588928918389e+26],"radius_km":[5504.8934633,5504.8934633],"distance_ly":[24.843331290684347,25.89029326315509],"host_mass_solar":[0.033,0.033],"inclination_deg":[0.29,0.29],"host_radius_solar":[0.04,0.04],"host_temperature_k":[100,100],"semi_major_axis_km":[52359.254745,52359.254745],"orbital_period_days":[0.000002,0.000002]},"host_mass_solar":1.334,"inclination_deg":81.18,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.524,"planets_in_system":1,"discovery_facility":"SuperWASP","host_spectral_type":"F4","host_temperature_k":6700,"orbital_period_days":2.7325321,"transit_midpoint_bjd":2456079.5642,"equilibrium_temperature_k":1942,"argument_of_periastron_deg":0},"designations":[{"catalog":"Exoplanet","designation":"WASP-93 b"},{"catalog":"Host star","designation":"WASP-93"}],"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.
