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-196114","name":"PGC 196114","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":15.243,"mag_band":"B","abs_mag":-19.97407240131932,"abs_mag_band":"B","distance_ly":360446120.4350941,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":354.909027,"dec_deg":-2.648755,"epoch_ra_deg":355.253763,"epoch_dec_deg":-2.500009,"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":"Pisces","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-196114","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.243,"h_mag":12.724,"j_mag":13.38,"k_mag":12.369,"redshift":0.02348,"redshift_cmb":0.0253193848750792,"uncertainties":{"distance_ly":[18045004.0873326,18050263.51662459],"stellar_mass_solar":[4670557431.753279,4670557431.753279]},"stellar_mass_solar":9341114863.506557},"designations":[{"catalog":"2MASX","designation":"2MASX 23393816-0238555"},{"catalog":"PGC","designation":"PGC 196114"},{"catalog":"WISExSCOS","designation":"WISExSCOS J233938.21-023855.7"}],"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.
