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-3067","name":"NGC 3067","class":"intermediate_spiral_galaxy_saba","category":"galaxy","object_type":"Intermediate spiral galaxy SABa","mag":12.13,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":81772909.38178954,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":149.58783333333335,"dec_deg":32.36988888888889,"epoch_ra_deg":149.98085,"epoch_dec_deg":32.241813,"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":"Leo","discovered":"1785","featured":false,"url":"https://spacecatalog.org/object/ngc-3067","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":12.73,"h_mag":9.16,"j_mag":9.89,"k_mag":8.9,"v_mag":12.13,"redshift":0.004922,"hubble_type":"SABa","wikidata_id":"Q1102771","redshift_cmb":0.00582823068398608,"discovered_by":"William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[14421493.464992216,14421493.464992216]},"major_axis_arcmin":2.06,"minor_axis_arcmin":0.66,"wikipedia_article":"NGC 3067","position_angle_deg":104,"surface_brightness":22.36,"radial_velocity_km_s":1472},"designations":[{"catalog":"2MASX","designation":"2MASX J09582105+3222119"},{"catalog":"IRAS","designation":"IRAS 09554+3236"},{"catalog":"IRAS","designation":"IRAS F09554+3236"},{"catalog":"LEDA","designation":"LEDA 28805"},{"catalog":"MCG","designation":"MCG +06-22-046"},{"catalog":"NGC","designation":"NGC 3067"},{"catalog":"PGC","designation":"PGC 28805"},{"catalog":"SDSS","designation":"SDSS J095821.07+322211.6"},{"catalog":"SDSS","designation":"SDSS J095821.08+322211.6"},{"catalog":"UGC","designation":"UGC 5351"}],"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.
