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-32-b","name":"HATS-32 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":2430.24335538789,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":346.0750861,"dec_deg":-21.2720168,"epoch_ra_deg":346.434014,"epoch_dec_deg":-21.127262,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HATS-32","semi_major_axis_km":6019818.316968,"periapsis_km":null,"mass_kg":1.7462833843465233e+27,"mass_msun":0.000878231,"constellation":"Aquarius","discovered":"2016","featured":false,"url":"https://spacecatalog.org/object/hats-32-b","radius_km":89293.6615021,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HATS-32","host_v_mag":14.386,"uncertainties":{"mass_kg":[1.8981341134201343e+26,1.8981341134201343e+26],"radius_km":[6863.2437984,10294.8656976],"distance_ly":[54.56922355578835,57.0871507917616],"host_mass_solar":[0.044,0.044],"inclination_deg":[1.2,1.2],"host_radius_solar":[0.063,0.098],"host_temperature_k":[110,110],"semi_major_axis_km":[79286.87147099999,79286.87147099999],"orbital_period_days":[0.0000055,0.0000055]},"host_mass_solar":1.099,"inclination_deg":87.1,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.097,"planets_in_system":1,"discovery_facility":"HATSouth","host_temperature_k":5700,"orbital_period_days":2.8126548,"transit_midpoint_bjd":2456454.6252,"eccentricity_upper_limit":0.471,"equilibrium_temperature_k":1437},"designations":[{"catalog":"Exoplanet","designation":"HATS-32 b"},{"catalog":"Host star","designation":"HATS-32"}],"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.
