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":"ic-5119","name":"IC 5119","class":"spiral_galaxy_sa","category":"galaxy","object_type":"Spiral galaxy Sa","mag":15.26,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":234504965.4653941,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":323.48270833333333,"dec_deg":21.837916666666665,"epoch_ra_deg":323.790313,"epoch_dec_deg":21.956895,"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":"Pegasus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-5119","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.26,"h_mag":10.74,"j_mag":11.46,"k_mag":10.41,"redshift":0.017689,"hubble_type":"Sa","wikidata_id":"Q3680643","redshift_cmb":0.01657958117414582,"ngc_type_code":"G","uncertainties":{"distance_ly":[17017202.0152815,17017202.0152815]},"major_axis_arcmin":0.82,"minor_axis_arcmin":0.23,"position_angle_deg":153,"surface_brightness":23.02,"radial_velocity_km_s":5256},"designations":[{"catalog":"2MASX","designation":"2MASX J21335584+2150164"},{"catalog":"IC","designation":"IC 5119"},{"catalog":"IRAS","designation":"IRAS 21316+2136"},{"catalog":"IRAS","designation":"IRAS F21316+2136"},{"catalog":"LEDA","designation":"LEDA 66969"},{"catalog":"PGC","designation":"PGC 66969"},{"catalog":"UGC","designation":"UGC 11766"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
