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-62-b","name":"HATS-62 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1706.0163802316383,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":312.4493079,"dec_deg":-24.303506,"epoch_ra_deg":312.843801,"epoch_dec_deg":-24.203867,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HATS-62","semi_major_axis_km":6227759.357240999,"periapsis_km":null,"mass_kg":3.39766006302204e+26,"mass_msun":0.000170873,"constellation":"Capricornus","discovered":"2018","featured":false,"url":"https://spacecatalog.org/object/hats-62-b","radius_km":75424.1896595,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HATS-62","host_v_mag":14.171,"uncertainties":{"radius_km":[1787.3030725,1787.3030725],"distance_ly":[32.723269376320864,34.00506394074767],"host_mass_solar":[0.01,0.015],"inclination_deg":[0.35,0.35],"host_radius_solar":[0.013,0.019],"host_temperature_k":[13,19],"semi_major_axis_km":[23935.659312,35903.488968],"orbital_period_days":[0.0000033,0.0000033]},"host_mass_solar":0.896,"inclination_deg":87.92,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.933,"planets_in_system":1,"discovery_facility":"HATSouth","host_temperature_k":5416,"orbital_period_days":3.2768837,"transit_midpoint_bjd":2455808.05158,"eccentricity_upper_limit":0.298,"equilibrium_temperature_k":1237},"designations":[{"catalog":"Exoplanet","designation":"HATS-62 b"},{"catalog":"Host star","designation":"HATS-62"}],"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.
