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-432-b","name":"Kepler-432 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":2765.881099004859,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":293.2822344,"dec_deg":48.2859173,"epoch_ra_deg":293.471225,"epoch_dec_deg":48.343147,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-432","semi_major_axis_km":45028959.080699995,"periapsis_km":null,"mass_kg":1.0268905553602924e+28,"mass_msun":0.00516438,"constellation":"Cygnus","discovered":"2015","featured":false,"url":"https://spacecatalog.org/object/kepler-432-b","radius_km":81858.48072050001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-432","host_v_mag":12.398,"eccentricity":0.5134,"uncertainties":{"mass_kg":[3.416641404156241e+26,6.074029162944429e+26],"radius_km":[2788.1927931,2573.7164244],"distance_ly":[65.77758747602422,65.77758747602422],"eccentricity":[0.0089,0.0098],"host_mass_solar":[0.07,0.1],"inclination_deg":[0.33,0.61],"host_radius_solar":[0.08,0.12],"host_temperature_k":[78,78],"semi_major_axis_km":[1645576.5776999998,2393565.9312],"orbital_period_days":[0.000053,0.000067],"argument_of_periastron_deg":[1.5,1.6]},"host_mass_solar":1.32,"inclination_deg":88.17,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":4.06,"planets_in_system":2,"discovery_facility":"Kepler","host_temperature_k":4995,"orbital_period_days":52.501129,"transit_midpoint_bjd":2455949.5374,"equilibrium_temperature_k":812,"argument_of_periastron_deg":64.1},"designations":[{"catalog":"Exoplanet","designation":"Kepler-432 b"},{"catalog":"Host star","designation":"Kepler-432"}],"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.
