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-1325","name":"NGC 1325","class":"barred_spiral_galaxy_sbbc","category":"galaxy","object_type":"Barred spiral galaxy SBbc","mag":11.54,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":68660760.63608022,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":51.106541666666665,"dec_deg":-21.544027777777778,"epoch_ra_deg":51.405435,"epoch_dec_deg":-21.448611,"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":"Eridanus","discovered":"1798","featured":false,"url":"https://spacecatalog.org/object/ngc-1325","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":12.25,"h_mag":8.91,"j_mag":9.49,"k_mag":8.63,"v_mag":11.54,"redshift":0.005359,"hubble_type":"SBbc","wikidata_id":"Q680118","redshift_cmb":0.00489713599265551,"discovered_by":"William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[14300362.756390331,14300362.756390331]},"major_axis_arcmin":4.32,"minor_axis_arcmin":1.5,"wikipedia_article":"NGC 1325","position_angle_deg":53,"surface_brightness":23.36,"radial_velocity_km_s":1602},"designations":[{"catalog":"2MASX","designation":"2MASX J03242556-2132385"},{"catalog":"ESO","designation":"ESO 548-007"},{"catalog":"ESO","designation":"ESO 548-7"},{"catalog":"ESO-LV","designation":"ESO-LV 548-0070"},{"catalog":"IRAS","designation":"IRAS 03221-2143"},{"catalog":"IRAS","designation":"IRAS 03222-2143"},{"catalog":"LEDA","designation":"LEDA 12737"},{"catalog":"MCG","designation":"MCG -04-09-004"},{"catalog":"NGC","designation":"NGC 1325"},{"catalog":"PGC","designation":"PGC 12737"},{"catalog":"UGCA","designation":"UGCA 70"}],"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.
