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":"eso-119-045","name":"ESO 119-045","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":15.778,"mag_band":"B","abs_mag":-20.42879648996869,"abs_mag_band":"B","distance_ly":568571613.3540076,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":78.590431,"dec_deg":-60.791153,"epoch_ra_deg":78.673374,"epoch_dec_deg":-60.759412,"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":"Dorado","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-119-045","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.778,"h_mag":12.139,"j_mag":12.664,"k_mag":11.739,"redshift":0.03852,"redshift_cmb":0.039528346037226,"uncertainties":{"distance_ly":[28841383.556352895,28855966.094768953],"stellar_mass_solar":[9340281815.197012,9340281815.197012]},"stellar_mass_solar":18680563630.394024},"designations":[{"catalog":"2MASX","designation":"2MASX 05142170-6047281"},{"catalog":"WISExSCOS","designation":"WISExSCOS J051421.80-604728.3"}],"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.
