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":"hip-97233-b","name":"HIP 97233 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":333.57643530979936,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":296.4221207,"dec_deg":-0.6968794,"epoch_ra_deg":296.767892,"epoch_dec_deg":-0.631975,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HIP 97233","semi_major_axis_km":372648295.9137,"periapsis_km":null,"mass_kg":3.6419316695538168e+28,"mass_msun":0.0183158,"constellation":"Aquila","discovered":"2014","featured":false,"url":"https://spacecatalog.org/object/hip-97233-b","radius_km":77175.01000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HIP 97233","host_v_mag":7.34,"eccentricity":0.63,"uncertainties":{"mass_kg":[6.149923703331218e+26,6.914867916907761e+27],"distance_ly":[1.3176717659756434,1.3274564573071457],"eccentricity":[0.042,0.044],"host_mass_solar":[0.104,0.104],"inclination_deg":[20.89,20.58],"host_radius_solar":[0.55,0.55],"host_temperature_k":[100,100],"semi_major_axis_km":[7629491.405699999,7330295.664299999],"orbital_period_days":[9.63078,8.8071],"argument_of_periastron_deg":[3.867,4.549]},"host_mass_solar":1.81,"inclination_deg":86.083,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":5.34,"planets_in_system":1,"discovery_facility":"Multiple Observatories","host_spectral_type":"K0/1 III","host_temperature_k":5020,"orbital_period_days":1062.26506,"periastron_epoch_bjd":2454786.725,"equilibrium_temperature_k":354.42,"argument_of_periastron_deg":249.249},"designations":[{"catalog":"Exoplanet","designation":"HIP 97233 b"},{"catalog":"Host star","designation":"HIP 97233"}],"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.
