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-196067-b","name":"HD 196067 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":130.24924481567064,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":310.4364195,"dec_deg":-75.3514992,"epoch_ra_deg":311.218143,"epoch_dec_deg":-75.255447,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 196067","semi_major_axis_km":704605970.997,"periapsis_km":null,"mass_kg":2.1638620437226617e+28,"mass_msun":0.0108824,"constellation":"Octans","discovered":"2012","featured":false,"url":"https://spacecatalog.org/object/hd-196067-b","radius_km":79088.44,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 196067","host_v_mag":6.51,"eccentricity":0.56292,"uncertainties":{"mass_kg":[3.036999359610753e+27,3.036999359610753e+27],"distance_ly":[0.15003193374970197,0.15003193374970197],"eccentricity":[0.00703,0.00703],"host_mass_solar":[0.09,0.13],"inclination_deg":[3.8,5],"host_radius_solar":[0.04,0.03],"host_temperature_k":[76,83],"semi_major_axis_km":[14959787.07,16455765.776999999],"orbital_period_days":[10.5,10.5],"argument_of_periastron_deg":[0.966,0.966]},"host_mass_solar":1.16,"inclination_deg":29.7,"stars_in_system":2,"discovery_method":"Radial Velocity","host_radius_solar":1.71,"planets_in_system":2,"discovery_facility":"La Silla Observatory","host_spectral_type":"G0 V","host_temperature_k":6072,"orbital_period_days":3413.7,"periastron_epoch_bjd":2453375,"equilibrium_temperature_k":176.42,"argument_of_periastron_deg":142.835},"designations":[{"catalog":"Exoplanet","designation":"HD 196067 b"},{"catalog":"Host star","designation":"HD 196067"}],"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.
