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":"kepler-1063-b","name":"Kepler-1063 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1119.4534889820698,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":290.5267975,"dec_deg":38.1428283,"epoch_ra_deg":290.760294,"epoch_dec_deg":38.193398,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-1063","semi_major_axis_km":17592709.59432,"periapsis_km":null,"mass_kg":1.6901235065849604e+25,"mass_msun":0.00000849987,"constellation":"Lyra","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kepler-1063-b","radius_km":9503.369,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-1063","host_v_mag":13.029,"eccentricity":0,"uncertainties":{"radius_km":[1211.8390000000002,2551.2400000000002],"host_mass_solar":[0.072,0.109],"host_radius_solar":[0.14,0.304],"host_temperature_k":[155.38,188.84],"orbital_period_days":[0.00002871,0.00002871]},"host_mass_solar":1.09,"inclination_deg":89.53,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":1.14,"planets_in_system":1,"discovery_facility":"Kepler","host_temperature_k":5945,"orbital_period_days":14.07971466,"transit_midpoint_bjd":2454972.95846,"equilibrium_temperature_k":931},"designations":[{"catalog":"Exoplanet","designation":"Kepler-1063 b"},{"catalog":"Host star","designation":"Kepler-1063"}],"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.
