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-185-b","name":"WASP-185 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":911.1178411517228,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":214.0595791,"dec_deg":-19.5423062,"epoch_ra_deg":214.43309,"epoch_dec_deg":-19.667226,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-185","semi_major_axis_km":13523647.511279998,"periapsis_km":null,"mass_kg":1.8601714311517316e+27,"mass_msun":0.000935507,"constellation":"Virgo","discovered":"2019","featured":false,"url":"https://spacecatalog.org/object/wasp-185-b","radius_km":89365.153625,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-185","host_v_mag":11.101,"eccentricity":0.24,"uncertainties":{"mass_kg":[1.1388804680520805e+26,1.1388804680520805e+26],"radius_km":[5719.369832,5719.369832],"distance_ly":[10.952331163728244,11.216517829678807],"eccentricity":[0.04,0.04],"host_mass_solar":[0.06,0.06],"inclination_deg":[0.3,0.3],"host_radius_solar":[0.08,0.08],"host_temperature_k":[100,100],"semi_major_axis_km":[254316.38018999997,254316.38018999997],"orbital_period_days":[0.00002,0.00002],"argument_of_periastron_deg":[7,7]},"host_mass_solar":1.12,"inclination_deg":86.8,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.5,"planets_in_system":1,"discovery_facility":"WASP-South","host_spectral_type":"G0 V","host_temperature_k":5900,"orbital_period_days":9.38755,"transit_midpoint_bjd":2456935.982,"equilibrium_temperature_k":1160,"argument_of_periastron_deg":-42},"designations":[{"catalog":"Exoplanet","designation":"WASP-185 b"},{"catalog":"Host star","designation":"WASP-185"}],"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.
