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-132-b","name":"TOI-132 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":533.8462359192113,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":338.3996623,"dec_deg":-43.436872,"epoch_ra_deg":338.79736,"epoch_dec_deg":-43.298486,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-132","semi_major_axis_km":3889544.6381999995,"periapsis_km":null,"mass_kg":1.337765602385269e+26,"mass_msun":0.0000672782,"constellation":"Grus","discovered":"2020","featured":false,"url":"https://spacecatalog.org/object/toi-132-b","radius_km":21813.102000000003,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-132","host_v_mag":11.197,"eccentricity":0.059,"uncertainties":{"mass_kg":[1.1466562306159448e+25,1.134711894880362e+25],"radius_km":[892.9340000000001,829.153],"distance_ly":[3.1995940654012527,3.2387328307272623],"eccentricity":[0.037,0.05],"host_mass_solar":[0.06,0.06],"inclination_deg":[1.84,1.3],"host_radius_solar":[0.02,0.02],"host_temperature_k":[46,46],"semi_major_axis_km":[448793.61209999997,299195.7414],"orbital_period_days":[0.000011,0.000012],"argument_of_periastron_deg":[38.05,57.23]},"host_mass_solar":0.97,"inclination_deg":85.03,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.9,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"G8 V","host_temperature_k":5397,"orbital_period_days":2.1097019,"transit_midpoint_bjd":2458333.23095,"equilibrium_temperature_k":1395,"argument_of_periastron_deg":125.88},"designations":[{"catalog":"Exoplanet","designation":"TOI-132 b"},{"catalog":"Host star","designation":"TOI-132"}],"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.
