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":"koi-7368-b","name":"KOI-7368 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":864.2980931304843,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":293.9476365,"dec_deg":48.0652589,"epoch_ra_deg":294.138606,"epoch_dec_deg":48.124099,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"KOI-7368","semi_major_axis_km":10142735.633459998,"periapsis_km":null,"mass_kg":3.3205253344920064e+25,"mass_msun":0.0000166994,"constellation":"Cygnus","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/koi-7368-b","radius_km":14159.382000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"KOI-7368","host_v_mag":12.969,"eccentricity":0,"uncertainties":{"radius_km":[765.3720000000001,765.3720000000001],"distance_ly":[5.2413329899080665,5.303302701674248],"host_mass_solar":[0.018,0.018],"host_radius_solar":[0.036,0.036],"host_temperature_k":[100,100],"orbital_period_days":[0.0000125,0.0000125]},"host_mass_solar":0.879,"inclination_deg":71.62,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.874,"planets_in_system":1,"discovery_facility":"Kepler","host_temperature_k":5241,"orbital_period_days":6.8430344,"transit_midpoint_bjd":2454970.0463,"equilibrium_temperature_k":805},"designations":[{"catalog":"Exoplanet","designation":"KOI-7368 b"},{"catalog":"Host star","designation":"KOI-7368"}],"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.
