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-1459265","name":"PGC 1459265","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":16.41,"mag_band":"B","abs_mag":-18.336100142558177,"abs_mag_band":"B","distance_ly":290165586.2881714,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":356.716034,"dec_deg":14.480728,"epoch_ra_deg":357.057427,"epoch_dec_deg":14.629893,"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-1459265","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":16.41,"h_mag":14.218,"j_mag":14.981,"k_mag":14.102,"redshift":0.0190031195016,"hubble_type":"5.84","redshift_cmb":0.0204558341135461,"uncertainties":{"distance_ly":[55945860.134918295,56239675.70939865],"stellar_mass_solar":[747312044.2869232,747312044.2869232]},"major_axis_arcmin":0.489117,"minor_axis_arcmin":0.390217,"morphology_source":"SIMBAD (2024ApJ...970...83B, quality C)","position_angle_deg":168,"stellar_mass_solar":1307796077.5021157},"designations":[{"catalog":"2MASX","designation":"2MASX 23465184+1428506"},{"catalog":"PGC","designation":"PGC 1459265"},{"catalog":"WISExSCOS","designation":"WISExSCOS J234651.86+142850.3"}],"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":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
