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-32215","name":"PGC 32215","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":15.624,"mag_band":"B","abs_mag":-19.233292284428714,"abs_mag_band":"B","distance_ly":305410758.85468197,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":161.769165,"dec_deg":37.561169,"epoch_ra_deg":162.150334,"epoch_dec_deg":37.419778,"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 Minor","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-32215","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.624,"h_mag":14.274,"j_mag":14.813,"k_mag":13.892,"redshift":0.02292,"redshift_cmb":0.0215137276490209,"uncertainties":{"distance_ly":[16109480.776979253,16114954.060218083],"stellar_mass_solar":[747307059.8733069,747307059.8733069]},"stellar_mass_solar":1681440884.7149405},"designations":[{"catalog":"2MASX","designation":"2MASX 10470459+3733402"},{"catalog":"PGC","designation":"PGC 32215"},{"catalog":"WISExSCOS","designation":"WISExSCOS J104704.65+373339.5"}],"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":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
