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":"hd-114386-b","name":"HD 114386 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":91.07688538275657,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":197.6652124,"dec_deg":-35.0561807,"epoch_ra_deg":198.040183,"epoch_dec_deg":-35.19926,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 114386","semi_major_axis_km":258804316.311,"periapsis_km":null,"mass_kg":2.771261915644812e+27,"mass_msun":0.00139371,"constellation":"Centaurus","discovered":"2003","featured":false,"url":"https://spacecatalog.org/object/hd-114386-b","radius_km":86742.16,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 114386","host_v_mag":8.73,"eccentricity":0.23,"uncertainties":{"mass_kg":[4.1758741194647855e+26,7.023061019099866e+26],"distance_ly":[0.13176717659756434,0.13176717659756434],"eccentricity":[0.03,0.03],"host_mass_solar":[0.09,0.09],"inclination_deg":[15,22],"host_radius_solar":[0.02,0.02],"host_temperature_k":[18,18],"semi_major_axis_km":[4487936.120999999,4487936.120999999],"orbital_period_days":[16,16],"argument_of_periastron_deg":[14,14]},"host_mass_solar":0.6,"inclination_deg":57,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.76,"planets_in_system":2,"discovery_facility":"La Silla Observatory","host_spectral_type":"K3 VC","host_temperature_k":4836,"orbital_period_days":937.70001,"periastron_epoch_bjd":2450454,"equilibrium_temperature_k":154.56,"argument_of_periastron_deg":273},"designations":[{"catalog":"Exoplanet","designation":"HD 114386 b"},{"catalog":"Host star","designation":"HD 114386"}],"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.
