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":"ngc-1316","name":"Fornax A","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0","mag":8.48,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":77884574.7947141,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":50.673833333333334,"dec_deg":-37.208222222222226,"epoch_ra_deg":50.931208,"epoch_dec_deg":-37.111957,"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":"Fornax","discovered":"1826","featured":false,"url":"https://spacecatalog.org/object/ngc-1316","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":9.41,"h_mag":5.87,"j_mag":6.45,"k_mag":5.59,"v_mag":8.48,"redshift":0.005911,"hubble_type":"S0","wikidata_id":"Q495785","redshift_cmb":0.005552255847068643,"discovered_by":"James Dunlop","ngc_type_code":"G","uncertainties":{"distance_ly":[14383657.374201642,14383657.374201642]},"major_axis_arcmin":13.46,"minor_axis_arcmin":7.71,"wikipedia_article":"NGC 1316","position_angle_deg":50,"surface_brightness":23.77,"radial_velocity_km_s":1767},"designations":[{"catalog":"2MASX","designation":"2MASX J03224178-3712295"},{"catalog":"Common name","designation":"Fornax A"},{"catalog":"ESO","designation":"ESO 357-022"},{"catalog":"ESO","designation":"ESO 357-22"},{"catalog":"ESO-LV","designation":"ESO-LV 357-0220"},{"catalog":"Fornax","designation":"Fornax A"},{"catalog":"IRAS","designation":"IRAS 03208-3723"},{"catalog":"IRAS","designation":"IRAS F03207-3723"},{"catalog":"LEDA","designation":"LEDA 12651"},{"catalog":"MCG","designation":"MCG -06-08-005"},{"catalog":"NGC","designation":"NGC 1316"},{"catalog":"PGC","designation":"PGC 12651"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
