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-1060499","name":"PGC 1060499","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":15.171,"mag_band":"B","abs_mag":-19.873582978752744,"abs_mag_band":"B","distance_ly":332921981.6054262,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":198.697968,"dec_deg":-4.276786,"epoch_ra_deg":199.045668,"epoch_dec_deg":-4.419037,"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":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-1060499","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.171,"h_mag":12.999,"j_mag":13.597,"k_mag":12.588,"redshift":0.02322,"redshift_cmb":0.0234187108432569,"uncertainties":{"distance_ly":[17625948.286589667,17631152.86966197],"stellar_mass_solar":[1868245298.1688955,1868245298.1688955]},"stellar_mass_solar":4670613245.422238},"designations":[{"catalog":"2MASX","designation":"2MASX 13144751-0416364"},{"catalog":"PGC","designation":"PGC 1060499"},{"catalog":"WISExSCOS","designation":"WISExSCOS J131447.49-041635.7"}],"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.
