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-14511","name":"PGC 14511","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":13.804,"mag_band":"B","abs_mag":-21.01164563011558,"abs_mag_band":"B","distance_ly":299609100.8398996,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":62.011284,"dec_deg":23.292896,"epoch_ra_deg":62.411782,"epoch_dec_deg":23.364615,"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":"Taurus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-14511","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.804,"h_mag":11.15,"j_mag":11.865,"k_mag":10.752,"redshift":0.02094,"hubble_type":"3","redshift_cmb":0.0211113294699623,"uncertainties":{"distance_ly":[18401744.782715768,18405398.477001224],"stellar_mass_solar":[9341362002.156622,9341362002.156622]},"major_axis_arcmin":0.5,"minor_axis_arcmin":0.48,"morphology_source":"SIMBAD (2005ApJS..160..149S, quality D)","position_angle_deg":20,"stellar_mass_solar":18682724004.313244},"designations":[{"catalog":"2MASX","designation":"2MASX 04080270+2317344"},{"catalog":"PGC","designation":"PGC 14511"},{"catalog":"WISExSCOS","designation":"WISExSCOS J040802.72+231733.8"}],"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.
