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-7049","name":"NGC 7049","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0","mag":10.55,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":94180927.70783794,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":319.75124999999997,"dec_deg":-48.56216666666666,"epoch_ra_deg":320.206192,"epoch_dec_deg":-48.449105,"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":"Indus","discovered":"1826","featured":false,"url":"https://spacecatalog.org/object/ngc-7049","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":11.67,"h_mag":7.59,"j_mag":8.14,"k_mag":7.25,"v_mag":10.55,"redshift":0.007315,"hubble_type":"S0","wikidata_id":"Q1139593","redshift_cmb":0.006708125983098778,"discovered_by":"James Dunlop","ngc_type_code":"G","uncertainties":{"distance_ly":[14552845.07590466,14552845.07590466]},"major_axis_arcmin":3.94,"minor_axis_arcmin":2.69,"wikipedia_article":"NGC 7049","position_angle_deg":64,"surface_brightness":23.38,"radial_velocity_km_s":2185},"designations":[{"catalog":"2MASX","designation":"2MASX J21190024-4833432"},{"catalog":"ESO","designation":"ESO 236-001"},{"catalog":"ESO","designation":"ESO 236-1"},{"catalog":"ESO-LV","designation":"ESO-LV 236-0010"},{"catalog":"IRAS","designation":"IRAS 21156-4846"},{"catalog":"IRAS","designation":"IRAS F21156-4846"},{"catalog":"LEDA","designation":"LEDA 66549"},{"catalog":"NGC","designation":"NGC 7049"},{"catalog":"PGC","designation":"PGC 66549"}],"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.
