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-035-011","name":"ESO 035-011","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":13.457,"mag_band":"B","abs_mag":-21.341225135415684,"abs_mag_band":"B","distance_ly":297215122.12624186,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":113.820663,"dec_deg":-76.918793,"epoch_ra_deg":113.570066,"epoch_dec_deg":-76.976796,"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":"Mensa","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-035-011","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.457,"h_mag":10.112,"j_mag":10.879,"k_mag":9.8,"redshift":0.01968,"hubble_type":"2.0","redshift_cmb":0.0209452168748123,"uncertainties":{"distance_ly":[15909598.204332469,15913106.124020133],"stellar_mass_solar":[18682743531.929302,18682743531.929302]},"major_axis_arcmin":0.88,"minor_axis_arcmin":0.669,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":55,"stellar_mass_solar":37365487063.858604},"designations":[{"catalog":"2MASX","designation":"2MASX 07351695-7655076"},{"catalog":"PGC","designation":"PGC 21340"},{"catalog":"WISExSCOS","designation":"WISExSCOS J073516.86-765507.4"}],"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.
