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-70801","name":"PGC 70801","class":"spiral_galaxy_sa","category":"galaxy","object_type":"Spiral galaxy SA","mag":15.462,"mag_band":"B","abs_mag":-19.302719050613586,"abs_mag_band":"B","distance_ly":292664256.94418037,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":348.715668,"dec_deg":33.02309,"epoch_ra_deg":349.039357,"epoch_dec_deg":33.169289,"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":"Pegasus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-70801","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.462,"h_mag":13.165,"j_mag":13.834,"k_mag":12.958,"redshift":0.019358,"hubble_type":"SA","redshift_cmb":0.0206293328916908,"uncertainties":{"distance_ly":[57050752.597182974,57355327.87150112],"stellar_mass_solar":[2802417094.1459723,2802417094.1459723]},"major_axis_arcmin":0.674173,"minor_axis_arcmin":0.254298,"morphology_source":"SIMBAD (2019MNRAS.488.2175B, quality C)","position_angle_deg":147,"stellar_mass_solar":4670695156.909954},"designations":[{"catalog":"2MASX","designation":"2MASX 23145176+3301231"},{"catalog":"PGC","designation":"PGC 70801"},{"catalog":"WISExSCOS","designation":"WISExSCOS J231451.66+330124.1"}],"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":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
