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-62034","name":"PGC 62034","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":14.479,"mag_band":"B","abs_mag":-20.50412443700185,"abs_mag_band":"B","distance_ly":323631482.45844054,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":278.402466,"dec_deg":48.23629,"epoch_ra_deg":278.580465,"epoch_dec_deg":48.256068,"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":"Draco","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-62034","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.479,"h_mag":10.943,"j_mag":11.643,"k_mag":10.709,"redshift":0.02304,"hubble_type":"2.5","redshift_cmb":0.0227759850265185,"uncertainties":{"distance_ly":[17359327.275887694,17364488.825972967],"stellar_mass_solar":[9341264169.610779,9341264169.610779]},"major_axis_arcmin":1.1871,"minor_axis_arcmin":0.795003,"morphology_source":"SIMBAD (2001ApJ...560..566K, quality D)","position_angle_deg":144,"stellar_mass_solar":18682528339.221558},"designations":[{"catalog":"2MASX","designation":"2MASX 18333659+4814106"},{"catalog":"PGC","designation":"PGC 62034"},{"catalog":"WISExSCOS","designation":"WISExSCOS J183336.60+481411.3"}],"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":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
