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-232-b","name":"Kepler-232 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":4400.273538689901,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":295.8161668,"dec_deg":51.1217249,"epoch_ra_deg":295.991972,"epoch_dec_deg":51.184948,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-232","semi_major_axis_km":8078285.0178,"periapsis_km":null,"mass_kg":5.787030663889846e+25,"mass_msun":0.0000291038,"constellation":"Cygnus","discovered":"2014","featured":false,"url":"https://spacecatalog.org/object/kepler-232-b","radius_km":19644.548000000003,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-232","host_v_mag":15.565,"eccentricity":0,"uncertainties":{"radius_km":[9375.807,9375.807],"distance_ly":[147.39006709019634,157.79445553936048],"host_mass_solar":[0.052,0.056],"host_radius_solar":[0.46,0.46],"host_temperature_k":[200,200],"orbital_period_days":[0.000011,0.000011]},"host_mass_solar":0.97,"inclination_deg":87.72,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.968,"planets_in_system":2,"discovery_facility":"Kepler","host_temperature_k":5847,"orbital_period_days":4.431222,"transit_midpoint_bjd":2455004.01551,"equilibrium_temperature_k":1104},"designations":[{"catalog":"Exoplanet","designation":"Kepler-232 b"}],"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
