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-7513","name":"NGC 7513","class":"barred_spiral_galaxy_sbb","category":"galaxy","object_type":"Barred spiral galaxy SBb","mag":11.8,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":59108453.23221495,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":348.3084583333333,"dec_deg":-28.3575,"epoch_ra_deg":348.669671,"epoch_dec_deg":-28.211523,"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":"Sculptor","discovered":"1864","featured":false,"url":"https://spacecatalog.org/object/ngc-7513","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":12.6,"h_mag":9.2,"j_mag":9.82,"k_mag":8.95,"v_mag":11.8,"redshift":0.00523,"hubble_type":"SBb","wikidata_id":"Q1167842","redshift_cmb":0.00421800228303848,"discovered_by":"Albert Marth","ngc_type_code":"G","uncertainties":{"distance_ly":[14223816.040239913,14223816.040239913]},"major_axis_arcmin":3.19,"minor_axis_arcmin":1.92,"wikipedia_article":"NGC 7513","position_angle_deg":100,"surface_brightness":23.48,"radial_velocity_km_s":1564},"designations":[{"catalog":"2MASX","designation":"2MASX J23131402-2821269"},{"catalog":"ESO","designation":"ESO 469-022"},{"catalog":"ESO","designation":"ESO 469-22"},{"catalog":"ESO-LV","designation":"ESO-LV 469-0220"},{"catalog":"IRAS","designation":"IRAS 23105-2837"},{"catalog":"LEDA","designation":"LEDA 70714"},{"catalog":"MCG","designation":"MCG -05-54-023"},{"catalog":"NGC","designation":"NGC 7513"},{"catalog":"PGC","designation":"PGC 70714"},{"catalog":"UGCA","designation":"UGCA 437"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
