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-69-b","name":"WASP-69 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":162.94935708917362,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":315.0259661,"dec_deg":-5.094857,"epoch_ra_deg":315.37966,"epoch_dec_deg":-4.990337,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"WASP-69","semi_major_axis_km":6776783.54271,"periapsis_km":null,"mass_kg":4.9318162252221206e+26,"mass_msun":0.000248028,"constellation":"Aquarius","discovered":"2014","featured":false,"url":"https://spacecatalog.org/object/wasp-69-b","radius_km":71498.501,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"WASP-69","host_v_mag":9.873,"eccentricity":0,"uncertainties":{"mass_kg":[3.2070541450039705e+25,3.2070541450039705e+25],"radius_km":[1403.182,1403.182],"distance_ly":[0.4282433239420841,0.43052641858610136],"host_mass_solar":[0.05,0.05],"inclination_deg":[0.04,0.04],"host_radius_solar":[0.015,0.015],"host_temperature_k":[158,158],"semi_major_axis_km":[119678.29656,119678.29656],"orbital_period_days":[1.3e-7,1.3e-7]},"host_mass_solar":0.83,"inclination_deg":86.79,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.801,"planets_in_system":1,"discovery_facility":"SuperWASP","host_spectral_type":"K","host_temperature_k":4792,"orbital_period_days":3.86813881,"transit_midpoint_bjd":2455748.83428,"equilibrium_temperature_k":971,"argument_of_periastron_deg":90},"designations":[{"catalog":"Exoplanet","designation":"WASP-69 b"},{"catalog":"Host star","designation":"WASP-69"}],"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.
