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-69225","name":"PGC 69225","class":"spiral_galaxy_sc","category":"galaxy","object_type":"Spiral galaxy Sc","mag":15.071,"mag_band":"B","abs_mag":-20.002207992063845,"abs_mag_band":"B","distance_ly":337339714.952778,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":338.749329,"dec_deg":37.199516,"epoch_ra_deg":339.050763,"epoch_dec_deg":37.33814,"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":"Lacerta","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-69225","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.071,"h_mag":12.828,"j_mag":13.55,"k_mag":12.687,"redshift":0.021904,"hubble_type":"Sc","redshift_cmb":0.0237241258033957,"uncertainties":{"distance_ly":[64922536.581464745,65310534.507789545],"stellar_mass_solar":[1868241696.4392602,1868241696.4392602]},"major_axis_arcmin":0.41,"minor_axis_arcmin":0.287,"morphology_source":"SIMBAD (2016MNRAS.456.2848H, quality D)","position_angle_deg":105,"stellar_mass_solar":3736483392.8785205},"designations":[{"catalog":"2MASX","designation":"2MASX 22345983+3711582"},{"catalog":"PGC","designation":"PGC 69225"},{"catalog":"WISExSCOS","designation":"WISExSCOS J223459.78+371158.5"}],"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
