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-2200-b","name":"TOI-2200 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":819.451591194432,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":98.7835071,"dec_deg":-72.4567778,"epoch_ra_deg":98.658656,"epoch_dec_deg":-72.477173,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2200","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":2.3112289648352638e+26,"mass_msun":0.000116235,"constellation":"Volans","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-2200-b","radius_km":44411.38108477701,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2200","host_v_mag":13.085,"uncertainties":{"radius_km":[2710.6075437080003,2725.418321061],"distance_ly":[3.858429948389075,3.8943071499379163],"host_mass_solar":[0.084336,0.123271],"inclination_deg":[1.03861,0.83738],"orbital_period_days":[0.00000140676,0.00000135637]},"host_mass_solar":0.85,"inclination_deg":88.6445,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.826247,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5036.17,"orbital_period_days":2.93602836512,"transit_midpoint_bjd":2459220.45229462,"equilibrium_temperature_k":1147},"designations":[{"catalog":"Exoplanet","designation":"TOI-2200 b"},{"catalog":"Host star","designation":"TOI-2200"}],"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.
