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-108341","name":"PGC 108341","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0...","mag":15.652,"mag_band":"B","abs_mag":-19.438048681075877,"abs_mag_band":"B","distance_ly":339966098.63423425,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":10.424525,"dec_deg":-38.369114,"epoch_ra_deg":10.748587,"epoch_dec_deg":-38.221788,"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":"Sculptor","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-108341","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.652,"h_mag":12.921,"j_mag":13.758,"k_mag":12.763,"redshift":0.02338,"hubble_type":"S0...","redshift_cmb":0.0239056343864038,"uncertainties":{"distance_ly":[17227169.84766577,17232606.497559782],"stellar_mass_solar":[1868239566.1443276,1868239566.1443276]},"major_axis_arcmin":0.52472,"minor_axis_arcmin":0.36573,"morphology_source":"SIMBAD (1996MNRAS.278.1025L, quality D)","position_angle_deg":21,"stellar_mass_solar":4670598915.360819},"designations":[{"catalog":"2MASX","designation":"2MASX 00414188-3822088"},{"catalog":"PGC","designation":"PGC 108341"},{"catalog":"WISExSCOS","designation":"WISExSCOS J004141.84-382208.1"}],"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":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
