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-34096","name":"PGC 34096","class":"elliptical_galaxy","category":"galaxy","object_type":"Elliptical galaxy","mag":14.707,"mag_band":"B","abs_mag":-20.204109179981167,"abs_mag_band":"B","distance_ly":313074511.2075754,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":168.129364,"dec_deg":23.276711,"epoch_ra_deg":168.487301,"epoch_dec_deg":23.130821,"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":"Leo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-34096","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.707,"h_mag":11.226,"j_mag":11.94,"k_mag":11.041,"redshift":0.02239,"hubble_type":"-4.2","redshift_cmb":0.0220449210430634,"uncertainties":{"distance_ly":[18816633.760995116,18821002.957590036],"stellar_mass_solar":[3736522882.788755,3736522882.788755]},"major_axis_arcmin":1.06299,"minor_axis_arcmin":0.818611,"morphology_source":"SIMBAD (2001ApJ...560..566K, quality D)","position_angle_deg":63,"stellar_mass_solar":31760444503.70442},"designations":[{"catalog":"2MASX","designation":"2MASX 11123104+2316361"},{"catalog":"PGC","designation":"PGC 34096"},{"catalog":"WISExSCOS","designation":"WISExSCOS J111231.02+231636.1"}],"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.
