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-67522-b","name":"HIP 67522 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":415.13183755787105,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":207.526001,"dec_deg":-40.8358961,"epoch_ra_deg":207.928766,"epoch_dec_deg":-40.969363,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HIP 67522","semi_major_axis_km":11189920.72836,"periapsis_km":null,"mass_kg":4.264127857603045e+26,"mass_msun":0.000214449,"constellation":"Centaurus","discovered":"2020","featured":false,"url":"https://spacecatalog.org/object/hip-67522-b","radius_km":63699.37180058,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HIP 67522","host_v_mag":9.79,"eccentricity":0.064,"uncertainties":{"radius_km":[1429.8399705410002,1501.331965879],"distance_ly":[3.545319825781001,3.6040279737700147],"eccentricity":[0.049,0.187],"host_mass_solar":[0.05,0.05],"inclination_deg":[0.93,1.08],"host_radius_solar":[0.06,0.06],"host_temperature_k":[75,75],"semi_major_axis_km":[269276.16725999996,239356.59312],"orbital_period_days":[0.0000022,0.0000022],"argument_of_periastron_deg":[50,140]},"host_mass_solar":1.22,"inclination_deg":89.88,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.38,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"G1 V","host_temperature_k":5675,"orbital_period_days":6.9594731,"transit_midpoint_bjd":2458604.02376,"equilibrium_temperature_k":1175,"argument_of_periastron_deg":195.3},"designations":[{"catalog":"Exoplanet","designation":"HIP 67522 b"},{"catalog":"Host star","designation":"HIP 67522"}],"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.
