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-2669-b","name":"TOI-2669 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1283.2394371800867,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":134.7226445,"dec_deg":-13.3125792,"epoch_ra_deg":135.041229,"epoch_dec_deg":-13.416473,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2669","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":1.1578560058515997e+27,"mass_msun":0.000582302,"constellation":"Hydra","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-2669-b","radius_km":125825.91963994301,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2669","host_v_mag":10.916,"eccentricity":0.09,"uncertainties":{"mass_kg":[3.606436739537769e+26,3.606436739537769e+26],"radius_km":[11438.719955671,11438.719955671],"distance_ly":[20.40434298995947,21.05991730917012],"eccentricity":[0.05,0.05],"host_mass_solar":[0.16,0.16],"host_radius_solar":[0.04,0.04],"host_temperature_k":[100,100],"orbital_period_days":[0.0001,0.0001],"argument_of_periastron_deg":[0.585,0.585]},"host_mass_solar":1.19,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":4.1,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4800,"orbital_period_days":6.2034,"transit_midpoint_bjd":2458521.598,"equilibrium_temperature_k":1226,"argument_of_periastron_deg":-1.22},"designations":[{"catalog":"Exoplanet","designation":"TOI-2669 b"},{"catalog":"Host star","designation":"TOI-2669"}],"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.
