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-322-085","name":"ESO 322-085","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":13.79,"mag_band":"B","abs_mag":-19.34070822456578,"abs_mag_band":"B","distance_ly":137901033.21799627,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":192.008774,"dec_deg":-40.594414,"epoch_ra_deg":192.378218,"epoch_dec_deg":-40.741093,"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-322-085","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.79,"h_mag":12.638,"j_mag":13.271,"k_mag":12.231,"redshift":0.0104397352199,"hubble_type":"5.0","redshift_cmb":0.0097992620657793,"uncertainties":{"distance_ly":[33600358.438792124,33681290.21356204],"stellar_mass_solar":[560521598.8457626,560521598.8457626]},"major_axis_arcmin":0.627,"minor_axis_arcmin":0.201,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":135,"stellar_mass_solar":840782398.268644},"designations":[{"catalog":"2MASX","designation":"2MASX 12480210-4035398"},{"catalog":"PGC","designation":"PGC 43214"},{"catalog":"WISExSCOS","designation":"WISExSCOS J124802.16-403539.5"}],"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":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
