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-92-b","name":"WASP-92 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1878.2987020691764,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":246.6920395,"dec_deg":51.0411328,"epoch_ra_deg":246.867577,"epoch_dec_deg":50.980056,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-92","semi_major_axis_km":5206005.900359999,"periapsis_km":null,"mass_kg":1.527997961303208e+27,"mass_msun":0.000768452,"constellation":"Hercules","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/wasp-92-b","radius_km":104449.99155690001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-92","host_v_mag":12.951,"eccentricity":0,"uncertainties":{"mass_kg":[1.2907311971256912e+26,1.2907311971256912e+26],"radius_km":[5504.8934633,5504.8934633],"distance_ly":[20.825084717214068,21.288226773571843],"host_mass_solar":[0.037,0.037],"inclination_deg":[0.69,0.69],"host_radius_solar":[0.058,0.058],"host_temperature_k":[120,120],"semi_major_axis_km":[53855.233452,53855.233452],"orbital_period_days":[0.0000016,0.0000016]},"host_mass_solar":1.19,"inclination_deg":83.75,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.341,"planets_in_system":1,"discovery_facility":"SuperWASP","host_spectral_type":"F7","host_temperature_k":6280,"orbital_period_days":2.1746742,"transit_midpoint_bjd":2456381.2834,"equilibrium_temperature_k":1871,"argument_of_periastron_deg":0},"designations":[{"catalog":"Exoplanet","designation":"WASP-92 b"},{"catalog":"Host star","designation":"WASP-92"}],"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.
