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-2202-b","name":"TOI-2202 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":769.5105266384443,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":51.2284214,"dec_deg":-73.9575458,"epoch_ra_deg":51.173524,"epoch_dec_deg":-73.862067,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2202","semi_major_axis_km":14307540.353748,"periapsis_km":null,"mass_kg":1.71590463819202e+27,"mass_msun":0.000862953,"constellation":"Hydrus","discovered":"2021","featured":false,"url":"https://spacecatalog.org/object/toi-2202-b","radius_km":69847.683782334,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2202","host_v_mag":13.004,"eccentricity":0.022,"uncertainties":{"mass_kg":[1.8981245997567207e+26,1.6513684018480686e+26],"radius_km":[1143.871989189,1143.871989189],"distance_ly":[3.3952878920312988,3.427903529802973],"eccentricity":[0.015,0.022],"host_mass_solar":[0.032,0.034],"inclination_deg":[0.12,0.17],"host_radius_solar":[0.022,0.024],"host_temperature_k":[78,80],"semi_major_axis_km":[240852.571827,233372.67829199997],"orbital_period_days":[0.00011,0.00011],"argument_of_periastron_deg":[94,59]},"host_mass_solar":0.841,"inclination_deg":89.29,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.808,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K8 V","host_temperature_k":5169,"orbital_period_days":11.9126075,"transit_midpoint_bjd":2459577.9736362,"equilibrium_temperature_k":652.07,"argument_of_periastron_deg":212},"designations":[{"catalog":"Exoplanet","designation":"TOI-2202 b"}],"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.
