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-7341","name":"NGC 7341","class":"intermediate_spiral_galaxy_saba","category":"galaxy","object_type":"Intermediate spiral galaxy SABa","mag":13.42,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":191697562.02910236,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":339.7730833333333,"dec_deg":-22.666666666666668,"epoch_ra_deg":340.139313,"epoch_dec_deg":-22.527039,"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":"Aquarius","discovered":"1885","featured":false,"url":"https://spacecatalog.org/object/ngc-7341","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.42,"h_mag":7.89,"j_mag":9.66,"k_mag":8.52,"redshift":0.01466,"hubble_type":"SABa","wikidata_id":"Q1167087","redshift_cmb":0.013583429249246715,"discovered_by":"Francis Preserved Leavenworth","ngc_type_code":"G","uncertainties":{"distance_ly":[16095997.517526899,16095997.517526899]},"major_axis_arcmin":2.39,"minor_axis_arcmin":0.95,"position_angle_deg":93,"surface_brightness":23.47,"radial_velocity_km_s":4363},"designations":[{"catalog":"2MASX","designation":"2MASX J22390552-2240001"},{"catalog":"ESO","designation":"ESO 534-011"},{"catalog":"ESO","designation":"ESO 534-11"},{"catalog":"ESO-LV","designation":"ESO-LV 534-0110"},{"catalog":"LEDA","designation":"LEDA 69412"},{"catalog":"MCG","designation":"MCG -04-53-027"},{"catalog":"NGC","designation":"NGC 7341"},{"catalog":"PGC","designation":"PGC 69412"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
