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-126045","name":"PGC 126045","class":"elliptical_galaxy_debc","category":"galaxy","object_type":"Elliptical galaxy dEbc","mag":17.32,"mag_band":"B","abs_mag":-15.591962630758225,"abs_mag_band":"B","distance_ly":124686203.44519539,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":201.111,"dec_deg":-3.47295,"epoch_ra_deg":201.45824,"epoch_dec_deg":-3.613065,"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":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-126045","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":17.32,"redshift":0.00858396429198,"hubble_type":"dEbc","redshift_cmb":0.0088664398813502,"uncertainties":{"distance_ly":[24950183.364356384,25010748.936748523],"stellar_mass_solar":[65394570.57391225,65394570.57391225]},"major_axis_arcmin":0.25,"minor_axis_arcmin":0.19,"morphology_source":"SIMBAD (2015ApJS..217...27A, quality C)","position_angle_deg":44,"stellar_mass_solar":102762896.61614782},"designations":[{"catalog":"PGC","designation":"PGC 126045"},{"catalog":"WISExSCOS","designation":"WISExSCOS J132426.64-032822.5"}],"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
