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-6349","name":"NGC 6349","class":"lenticular_galaxy_s0_a","category":"galaxy","object_type":"Lenticular galaxy S0-a","mag":15.2,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":551684491.1555164,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":259.77729166666666,"dec_deg":36.060916666666664,"epoch_ra_deg":260.014695,"epoch_dec_deg":36.032395,"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":"Hercules","discovered":"1879","featured":false,"url":"https://spacecatalog.org/object/ngc-6349","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.2,"h_mag":11.05,"j_mag":11.7,"k_mag":10.69,"redshift":0.03851,"hubble_type":"S0-a","wikidata_id":"Q1145256","redshift_cmb":0.03838589977904805,"discovered_by":"Édouard Stephan","ngc_type_code":"G","uncertainties":{"distance_ly":[26472495.535257887,26472495.535257887]},"major_axis_arcmin":1.07,"minor_axis_arcmin":0.25,"position_angle_deg":80,"surface_brightness":23.96,"radial_velocity_km_s":11324},"designations":[{"catalog":"2MASX","designation":"2MASX J17190654+3603389"},{"catalog":"LEDA","designation":"LEDA 60060"},{"catalog":"MCG","designation":"MCG +06-38-016"},{"catalog":"NGC","designation":"NGC 6349"},{"catalog":"PGC","designation":"PGC 60060"},{"catalog":"SDSS","designation":"SDSS J171906.54+360339.3"}],"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.
