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":"toi-3160-a-b","name":"TOI-3160 A b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1851.5180018948547,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":224.5658555,"dec_deg":-27.6825503,"epoch_ra_deg":224.964628,"epoch_dec_deg":-27.790367,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-3160 A","semi_major_axis_km":7554692.47035,"periapsis_km":null,"mass_kg":2.2587682737104976e+27,"mass_msun":0.00113597,"constellation":"Hydra","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-3160-a-b","radius_km":87792.17576023,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-3160 A","host_v_mag":12.649,"uncertainties":{"mass_kg":[2.8471868996350808e+26,3.036999359610753e+26],"radius_km":[3217.139981553,3288.6319768910002],"distance_ly":[106.11823905391964,119.60480527250698],"host_mass_solar":[0.078,0.082],"inclination_deg":[0.33,0.33],"host_radius_solar":[0.041,0.042],"host_temperature_k":[170,170],"semi_major_axis_km":[179517.44483999998,179517.44483999998],"orbital_period_days":[0.0000025,0.0000025]},"host_mass_solar":1.088,"inclination_deg":84.63,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":1.346,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":6190,"orbital_period_days":3.971281,"transit_midpoint_bjd":2459609.9851,"eccentricity_upper_limit":0.18,"equilibrium_temperature_k":1539},"designations":[{"catalog":"Exoplanet","designation":"TOI-3160 A b"},{"catalog":"Host star","designation":"TOI-3160 A"}],"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.
