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-2145-b","name":"TOI-2145 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":732.9744892066146,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":263.7580753,"dec_deg":40.6950428,"epoch_ra_deg":263.974673,"epoch_dec_deg":40.676777,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2145","semi_major_axis_km":16710082.157189997,"periapsis_km":null,"mass_kg":1.0781347726618174e+28,"mass_msun":0.0054221,"constellation":"Hercules","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-2145-b","radius_km":78069.26375645201,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2145","host_v_mag":9.07,"eccentricity":0.214,"uncertainties":{"mass_kg":[6.45362363917285e+26,7.023061019099866e+26],"radius_km":[2001.7759970260004,2144.759987702],"distance_ly":[3.5616276446668382,3.5942432824385127],"eccentricity":[0.014,0.014],"host_mass_solar":[0.04,0.04],"inclination_deg":[0.6,0.7],"host_radius_solar":[0.05,0.06],"host_temperature_k":[75,81],"semi_major_axis_km":[508632.76037999993,523592.54744999995],"orbital_period_days":[0.000007,0.000009],"argument_of_periastron_deg":[2.5,2.4]},"host_mass_solar":1.71,"inclination_deg":88.6,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":2.75,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":6206,"orbital_period_days":10.261128,"transit_midpoint_bjd":2458982.49662,"equilibrium_temperature_k":1484,"argument_of_periastron_deg":96.2},"designations":[{"catalog":"Exoplanet","designation":"TOI-2145 b"},{"catalog":"Host star","designation":"TOI-2145"}],"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.
