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-11063","name":"PGC 11063","class":"lenticular_galaxy","category":"galaxy","object_type":"Lenticular galaxy","mag":14.961,"mag_band":"B","abs_mag":-19.960672412580664,"abs_mag_band":"B","distance_ly":314601187.5999856,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":43.927891,"dec_deg":6.348418,"epoch_ra_deg":44.283349,"epoch_dec_deg":6.457352,"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":"Cetus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-11063","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.961,"h_mag":11.797,"j_mag":12.557,"k_mag":11.515,"redshift":0.02255,"hubble_type":"-2","redshift_cmb":0.0221506901160812,"uncertainties":{"distance_ly":[18769396.694074612,18773871.59611672],"stellar_mass_solar":[2802390260.665501,2802390260.665501]},"major_axis_arcmin":0.707317,"minor_axis_arcmin":0.324305,"morphology_source":"SIMBAD (2005ApJS..160..149S, quality D)","position_angle_deg":11,"stellar_mass_solar":25221512345.98951},"designations":[{"catalog":"2MASX","designation":"2MASX 02554269+0620543"},{"catalog":"PGC","designation":"PGC 11063"},{"catalog":"WISExSCOS","designation":"WISExSCOS J025542.70+062054.4"}],"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":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
