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-235-083","name":"ESO 235-083","class":"lenticular_galaxy","category":"galaxy","object_type":"Lenticular galaxy","mag":14.344,"mag_band":"B","abs_mag":-17.99304088753803,"abs_mag_band":"B","distance_ly":95682838.98998535,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":319.469177,"dec_deg":-48.313213,"epoch_ra_deg":319.923918,"epoch_dec_deg":-48.200622,"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":"Indus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-235-083","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.344,"h_mag":11.452,"j_mag":12.118,"k_mag":11.301,"redshift":0.00676,"hubble_type":"-0.8","redshift_cmb":0.0068145528597351,"uncertainties":{"distance_ly":[6017793.5189765245,6018167.5610659085],"stellar_mass_solar":[467110100.83458143,467110100.83458143]},"major_axis_arcmin":0.988407,"minor_axis_arcmin":0.82957,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":55,"stellar_mass_solar":934220201.6691629},"designations":[{"catalog":"2MASX","designation":"2MASX 21175260-4818475"},{"catalog":"PGC","designation":"PGC 66517"},{"catalog":"WISExSCOS","designation":"WISExSCOS J211752.58-481848"}],"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.
