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-507-032","name":"ESO 507-032","class":"lenticular_galaxy","category":"galaxy","object_type":"Lenticular galaxy","mag":13.129,"mag_band":"B","abs_mag":-20.46847580621514,"abs_mag_band":"B","distance_ly":170970442.7876033,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":193.061813,"dec_deg":-26.303967,"epoch_ra_deg":193.421916,"epoch_dec_deg":-26.450081,"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":"Hydra","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-507-032","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.129,"h_mag":9.63,"j_mag":10.354,"k_mag":9.393,"redshift":0.01162,"hubble_type":"-3.0","redshift_cmb":0.0121279471259881,"uncertainties":{"distance_ly":[11434464.8801766,11435466.658673413],"stellar_mass_solar":[4670944998.440162,4670944998.440162]},"major_axis_arcmin":1.117,"minor_axis_arcmin":0.715,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":65,"stellar_mass_solar":34564992988.4572},"designations":[{"catalog":"2MASX","designation":"2MASX 12521483-2618142"},{"catalog":"PGC","designation":"PGC 43649"},{"catalog":"WISExSCOS","designation":"WISExSCOS J125214.84-261814.1"}],"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":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
