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":"kic-3526061-b","name":"KIC 3526061 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1308.6339727491124,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":285.1863974,"dec_deg":38.6111112,"epoch_ra_deg":285.414877,"epoch_dec_deg":38.648361,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"KIC 3526061","semi_major_axis_km":768933055.3979999,"periapsis_km":null,"mass_kg":3.445096148558448e+28,"mass_msun":0.0173259,"constellation":"Lyra","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/kic-3526061-b","radius_km":77175.01000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"KIC 3526061","host_v_mag":10.372,"eccentricity":0.85,"uncertainties":{"mass_kg":[8.351748238929571e+26,8.351748238929571e+26],"distance_ly":[15.707691150838363,15.707691150838363],"eccentricity":[0.01,0.01],"host_mass_solar":[0.041,0.041],"host_radius_solar":[0.22,0.24],"host_temperature_k":[102,102],"semi_major_axis_km":[23935659.312,23935659.312],"orbital_period_days":[135,158],"argument_of_periastron_deg":[1.3,1.3]},"host_mass_solar":1.42,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":5.86,"planets_in_system":1,"discovery_facility":"McDonald Observatory","host_temperature_k":4829,"orbital_period_days":3552,"periastron_epoch_bjd":2458701.7,"transit_midpoint_bjd":2458708.1,"equilibrium_temperature_k":248.63,"argument_of_periastron_deg":75.7},"designations":[{"catalog":"Exoplanet","designation":"KIC 3526061 b"},{"catalog":"Host star","designation":"KIC 3526061"}],"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.
