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-1079","name":"NGC 1079","class":"intermediate_spiral_galaxy_saba","category":"galaxy","object_type":"Intermediate spiral galaxy SABa","mag":11.44,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":60175439.04047197,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":40.93475,"dec_deg":-29.00336111111111,"epoch_ra_deg":41.225468,"epoch_dec_deg":-28.889155,"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":"1835","featured":false,"url":"https://spacecatalog.org/object/ngc-1079","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":12.32,"h_mag":8.55,"j_mag":9.27,"k_mag":8.34,"v_mag":11.44,"redshift":0.004869,"hubble_type":"SABa","wikidata_id":"Q1041370","redshift_cmb":0.004293895568422634,"discovered_by":"John Frederick William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[14231870.822287709,14231870.822287709]},"major_axis_arcmin":2.65,"minor_axis_arcmin":1.49,"wikipedia_article":"NGC 1079","position_angle_deg":99,"surface_brightness":22.99,"radial_velocity_km_s":1456},"designations":[{"catalog":"2MASX","designation":"2MASX J02434435-2900123"},{"catalog":"ESO","designation":"ESO 416-013"},{"catalog":"ESO","designation":"ESO 416-13"},{"catalog":"ESO-LV","designation":"ESO-LV 416-0130"},{"catalog":"IRAS","designation":"IRAS 02415-2913"},{"catalog":"IRAS","designation":"IRAS F02415-2912"},{"catalog":"LEDA","designation":"LEDA 10330"},{"catalog":"MCG","designation":"MCG -05-07-017"},{"catalog":"NGC","designation":"NGC 1079"},{"catalog":"PGC","designation":"PGC 10330"}],"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.
