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-1268-b","name":"TOI-1268 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":357.3271427351326,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":198.3885831,"dec_deg":62.3053799,"epoch_ra_deg":198.646745,"epoch_dec_deg":62.162816,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1268","semi_major_axis_km":10636408.60677,"periapsis_km":null,"mass_kg":5.75716982455089e+26,"mass_msun":0.000289536,"constellation":"Ursa Major","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-1268-b","radius_km":58040.71,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1268","host_v_mag":10.92,"eccentricity":0.105,"uncertainties":{"mass_kg":[4.956899330266845e+25,4.8971776515889305e+25],"radius_km":[3826.86,3826.86],"distance_ly":[1.7612444396704146,1.7775522585562518],"eccentricity":[0.039,0.04],"host_mass_solar":[0.04,0.04],"inclination_deg":[0.3,0.32],"host_radius_solar":[0.06,0.06],"host_temperature_k":[100,100],"semi_major_axis_km":[867667.6500599999,942466.5854099999],"orbital_period_days":[0.0000045,0.0000045],"argument_of_periastron_deg":[19.5,20.7]},"host_mass_solar":0.96,"inclination_deg":88.63,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.92,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K1-K2","host_temperature_k":5300,"orbital_period_days":8.1577094,"transit_midpoint_bjd":2458711.7477,"equilibrium_temperature_k":918.9,"argument_of_periastron_deg":-40.6},"designations":[{"catalog":"Exoplanet","designation":"TOI-1268 b"},{"catalog":"Host star","designation":"TOI-1268"}],"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.
