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-7333-b","name":"TOI-7333 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":512.7732723549325,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":243.5319622,"dec_deg":75.9166315,"epoch_ra_deg":243.348356,"epoch_dec_deg":75.847662,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-7333","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":3.009972605366855e+25,"mass_msun":0.0000151376,"constellation":"Ursa Minor","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-7333-b","radius_km":13360.168821896,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-7333","host_v_mag":13.102,"uncertainties":{"radius_km":[1122.1341487690001,1312.3941473890002],"distance_ly":[1.8460450978767675,1.8623529167626047],"host_mass_solar":[0.08497,0.082159],"inclination_deg":[2.168,1.58211],"orbital_period_days":[0.0000304197,0.00003333784]},"host_mass_solar":0.721,"inclination_deg":87.78022,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.666066,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4586.87,"orbital_period_days":6.26449803661,"transit_midpoint_bjd":2459613.83792518,"equilibrium_temperature_k":755},"designations":[{"catalog":"Exoplanet","designation":"TOI-7333 b"},{"catalog":"Host star","designation":"TOI-7333"}],"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.
