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-532-b","name":"TOI-532 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":440.46440341513045,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":85.0800537,"dec_deg":11.5626373,"epoch_ra_deg":85.454749,"epoch_dec_deg":11.577263,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-532","semi_major_axis_km":4428096.97272,"periapsis_km":null,"mass_kg":3.6728832386916985e+26,"mass_msun":0.000184715,"constellation":"Orion","discovered":"2021","featured":false,"url":"https://spacecatalog.org/object/toi-532-b","radius_km":37120.542,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-532","host_v_mag":14.413,"eccentricity":0,"uncertainties":{"mass_kg":[5.554116117045983e+25,5.793002831757638e+25],"radius_km":[1211.8390000000002,1211.8390000000002],"distance_ly":[1.787336949887754,1.787336949887754],"host_mass_solar":[0.023,0.023],"inclination_deg":[0.41,0.51],"host_radius_solar":[0.012,0.013],"host_temperature_k":[37,37],"semi_major_axis_km":[52359.254745,52359.254745],"orbital_period_days":[0.000003,0.000003]},"host_mass_solar":0.639,"inclination_deg":88.08,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.612,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":3927,"orbital_period_days":2.3266508,"transit_midpoint_bjd":2458470.576777,"equilibrium_temperature_k":867,"argument_of_periastron_deg":90},"designations":[{"catalog":"Exoplanet","designation":"TOI-532 b"},{"catalog":"Host star","designation":"TOI-532"}],"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.
