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-1514-b","name":"Kepler-1514 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1295.7931961584043,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":292.6274943,"dec_deg":37.8601653,"epoch_ra_deg":292.863666,"epoch_dec_deg":37.915874,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-1514","semi_major_axis_km":112647196.6371,"periapsis_km":null,"mass_kg":1.0022148118858307e+28,"mass_msun":0.00504028,"constellation":"Cygnus","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/kepler-1514-b","radius_km":79213.2721732,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-1514","host_v_mag":11.766,"eccentricity":0.401,"uncertainties":{"mass_kg":[4.175895049524295e+26,4.175895049524295e+26],"radius_km":[1644.3188267,1644.3188267],"distance_ly":[13.173456095979265,13.444165889484163],"eccentricity":[0.014,0.013],"host_mass_solar":[0.063,0.065],"inclination_deg":[0.01,0.013],"host_radius_solar":[0.026,0.027],"host_temperature_k":[80,99],"semi_major_axis_km":[2094370.1897999998,1944772.3190999997],"orbital_period_days":[0.00012,0.00012],"argument_of_periastron_deg":[0.71,0.75]},"host_mass_solar":1.196,"inclination_deg":89.944,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.289,"planets_in_system":2,"discovery_facility":"Kepler","host_temperature_k":6145,"orbital_period_days":217.83184,"periastron_epoch_bjd":2454981.75,"transit_midpoint_bjd":2455071.81411,"equilibrium_temperature_k":387.9,"argument_of_periastron_deg":-75.28},"designations":[{"catalog":"Exoplanet","designation":"Kepler-1514 b"},{"catalog":"Host star","designation":"Kepler-1514"}],"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.
