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-5334","name":"NGC 5334","class":"spiral_galaxy_sc","category":"galaxy","object_type":"Spiral galaxy Sc","mag":11.73,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":77587240.37500314,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":208.22691666666668,"dec_deg":-1.114638888888889,"epoch_ra_deg":208.572434,"epoch_dec_deg":-1.247244,"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":"Virgo","discovered":"1787","featured":false,"url":"https://spacecatalog.org/object/ngc-5334","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.02,"h_mag":10.16,"j_mag":10.82,"k_mag":9.94,"v_mag":11.73,"redshift":0.00459,"hubble_type":"Sc","wikidata_id":"Q1118865","redshift_cmb":0.00553114779731656,"discovered_by":"William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[14380830.19245934,14380830.19245934]},"major_axis_arcmin":3.38,"minor_axis_arcmin":2.44,"wikipedia_article":"NGC 5334","position_angle_deg":17,"surface_brightness":24.15,"radial_velocity_km_s":1373},"designations":[{"catalog":"2MASX","designation":"2MASX J13525447-0106531"},{"catalog":"IC","designation":"IC 4338"},{"catalog":"IRAS","designation":"IRAS 13502-0051"},{"catalog":"IRAS","designation":"IRAS F13503-0052"},{"catalog":"LEDA","designation":"LEDA 49308"},{"catalog":"MCG","designation":"MCG +00-35-024"},{"catalog":"NGC","designation":"NGC 5334"},{"catalog":"PGC","designation":"PGC 49308"},{"catalog":"SDSS","designation":"SDSS J135254.45-010652.6"},{"catalog":"SDSS","designation":"SDSS J135254.46-010652.6"},{"catalog":"SDSS","designation":"SDSS J135254.46-010652.7"},{"catalog":"SDSS","designation":"SDSS J135254.50-010653.3"},{"catalog":"UGC","designation":"UGC 8790"}],"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.
