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-5267","name":"IC 5267","class":"lenticular_galaxy_s0_a","category":"galaxy","object_type":"Lenticular galaxy S0-a","mag":10.43,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":68855952.67621619,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":344.30654166666665,"dec_deg":-43.39613888888889,"epoch_ra_deg":344.690298,"epoch_dec_deg":-43.252739,"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":"Grus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-5267","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":11.39,"h_mag":7.68,"j_mag":8.29,"k_mag":7.45,"v_mag":10.43,"redshift":0.005701,"hubble_type":"S0-a","wikidata_id":"Q3102221","redshift_cmb":0.004911006173732302,"ngc_type_code":"G","uncertainties":{"distance_ly":[14302030.519524377,14302030.519524377]},"major_axis_arcmin":5.58,"minor_axis_arcmin":4.06,"position_angle_deg":138,"surface_brightness":23.84,"radial_velocity_km_s":1704},"designations":[{"catalog":"2MASX","designation":"2MASX J22571357-4323461"},{"catalog":"ESO","designation":"ESO 290-029"},{"catalog":"ESO","designation":"ESO 290-29"},{"catalog":"ESO-LV","designation":"ESO-LV 290-0290"},{"catalog":"IC","designation":"IC 5267"},{"catalog":"IRAS","designation":"IRAS 22543-4339"},{"catalog":"IRAS","designation":"IRAS F22543-4339"},{"catalog":"LEDA","designation":"LEDA 70094"},{"catalog":"MCG","designation":"MCG -07-47-007"},{"catalog":"PGC","designation":"PGC 70094"}],"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.
