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-322-041","name":"ESO 322-041","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":16.18,"mag_band":"B","abs_mag":-16.25919863894157,"abs_mag_band":"B","distance_ly":100291840.888305,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":189.662,"dec_deg":-40.48989,"epoch_ra_deg":190.026258,"epoch_dec_deg":-40.637697,"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":"Centaurus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-322-041","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":16.18,"redshift":0.00889749444875,"hubble_type":"7.5","redshift_cmb":0.0071410451569431,"uncertainties":{"distance_ly":[26386745.677394018,26450480.262857072],"stellar_mass_solar":[37368731.33709621,37368731.33709621]},"major_axis_arcmin":0.98,"minor_axis_arcmin":0.22,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":36,"stellar_mass_solar":46710914.17137026},"designations":[{"catalog":"PGC","designation":"PGC 42269"},{"catalog":"WISExSCOS","designation":"WISExSCOS J123839.03-402922.1"}],"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":"2026-09-09T11:17:28.634Z","attribution":"Data from SpaceCatalog.org.
