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":"ugc-11058","name":"UGC 11058","class":"barred_spiral_galaxy_sbbc","category":"galaxy","object_type":"Barred spiral galaxy SBbc","mag":13.281,"mag_band":"B","abs_mag":-20.94846468709909,"abs_mag_band":"B","distance_ly":228727726.19269896,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":269.229279,"dec_deg":32.636597,"epoch_ra_deg":269.477762,"epoch_dec_deg":32.632611,"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":"Hercules","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ugc-11058","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.281,"h_mag":10.91,"j_mag":11.624,"k_mag":10.659,"redshift":0.01587,"hubble_type":"SBbc","redshift_cmb":0.0161759915704326,"uncertainties":{"distance_ly":[12463532.277971344,12465876.779258532],"stellar_mass_solar":[2802495595.2259707,2802495595.2259707]},"major_axis_arcmin":1.58091,"minor_axis_arcmin":1.11075,"morphology_source":"SIMBAD (2008A&A...487..485H, quality D)","position_angle_deg":51,"stellar_mass_solar":5604991190.4519415},"designations":[{"catalog":"2MASX","designation":"2MASX 17565502+3238117"},{"catalog":"PGC","designation":"PGC 61155"},{"catalog":"WISExSCOS","designation":"WISExSCOS J175655.06+323812"}],"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.
