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":"pgc-1032359","name":"PGC 1032359","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":17.25,"mag_band":"B","abs_mag":-16.87224195305466,"abs_mag_band":"B","distance_ly":217707938.69080618,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":154.932709,"dec_deg":-6.481275,"epoch_ra_deg":155.269339,"epoch_dec_deg":-6.615924,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Sextans","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-1032359","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":17.25,"h_mag":14.502,"j_mag":15.128,"k_mag":14.178,"redshift":0.0147102973551,"redshift_cmb":0.0154055030928316,"uncertainties":{"distance_ly":[42938423.909367815,43115804.04091417],"stellar_mass_solar":[373667888.116835,373667888.116835]},"stellar_mass_solar":653918804.2044615},"designations":[{"catalog":"2MASX","designation":"2MASX 10194385-0628525"},{"catalog":"PGC","designation":"PGC 1032359"},{"catalog":"WISExSCOS","designation":"WISExSCOS J101943.84-062853.5"}],"source":{"id":"glade_plus","name":"GLADE+ (Galaxy List for the Advanced Detector Era)","url":"https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/291","license":"VizieR terms; cite Dalya+ 2022 (2022MNRAS.514.1403D)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
