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-70262","name":"PGC 70262","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":15.401,"mag_band":"B","abs_mag":-19.821784058831742,"abs_mag_band":"B","distance_ly":361395455.4265096,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":345.278748,"dec_deg":19.608776,"epoch_ra_deg":345.608573,"epoch_dec_deg":19.752895,"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-70262","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.401,"h_mag":12.908,"j_mag":13.605,"k_mag":12.693,"redshift":0.024378,"hubble_type":"E","redshift_cmb":0.025384848812502,"uncertainties":{"distance_ly":[72122571.38225871,72604122.29292607],"stellar_mass_solar":[4670555549.45214,4670555549.45214]},"major_axis_arcmin":0.46496,"minor_axis_arcmin":0.371178,"morphology_source":"SIMBAD (2003A&A...412...45P, quality E)","position_angle_deg":75,"stellar_mass_solar":8406999989.013851},"designations":[{"catalog":"2MASX","designation":"2MASX 23010689+1936315"},{"catalog":"PGC","designation":"PGC 70262"},{"catalog":"WISExSCOS","designation":"WISExSCOS J230107.00+193632.1"}],"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":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
