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":"hats-67-b","name":"HATS-67 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":3131.4567365324483,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":180.2087883,"dec_deg":-46.1364201,"epoch_ra_deg":180.551355,"epoch_dec_deg":-46.285876,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HATS-67","semi_major_axis_km":4535807.439623999,"periapsis_km":null,"mass_kg":2.752294464459194e+27,"mass_msun":0.00138417,"constellation":"Centaurus","discovered":"2018","featured":false,"url":"https://spacecatalog.org/object/hats-67-b","radius_km":120464.2270865,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HATS-67","host_v_mag":13.698,"uncertainties":{"mass_kg":[2.277760936104161e+26,2.277760936104161e+26],"radius_km":[3360.1297763000002,3360.1297763000002],"distance_ly":[74.68981049713423,78.3590697464476],"host_mass_solar":[0.021,0.021],"inclination_deg":[0.26,0.26],"host_radius_solar":[0.026,0.026],"host_temperature_k":[33,33],"semi_major_axis_km":[22439.680604999998,22439.680604999998],"orbital_period_days":[0.000004,0.000004]},"host_mass_solar":1.435,"inclination_deg":79.03,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.441,"planets_in_system":1,"discovery_facility":"HATSouth","host_temperature_k":6594,"orbital_period_days":1.6091788,"transit_midpoint_bjd":2457796.88127,"eccentricity_upper_limit":0.057,"equilibrium_temperature_k":2193},"designations":[{"catalog":"Exoplanet","designation":"HATS-67 b"},{"catalog":"Host star","designation":"HATS-67"}],"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":"2026-08-27T16:03:54.983Z","attribution":"Data from SpaceCatalog.org.
