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-3467","name":"NGC 3467","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0","mag":13.43,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":468124240.67862016,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":164.18366666666668,"dec_deg":9.758916666666666,"epoch_ra_deg":164.534968,"epoch_dec_deg":9.615584,"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":"1828","featured":false,"url":"https://spacecatalog.org/object/ngc-3467","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.42,"h_mag":10.63,"j_mag":11.32,"k_mag":10.4,"v_mag":13.43,"redshift":0.03149,"hubble_type":"S0","wikidata_id":"Q1104913","redshift_cmb":0.0327060670783923,"discovered_by":"John Frederick William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[23681195.685393114,23681195.685393114]},"major_axis_arcmin":0.92,"minor_axis_arcmin":0.81,"position_angle_deg":20,"surface_brightness":22.98,"radial_velocity_km_s":9292},"designations":[{"catalog":"2MASX","designation":"2MASX J10564407+0945324"},{"catalog":"LEDA","designation":"LEDA 32903"},{"catalog":"MCG","designation":"MCG +02-28-030"},{"catalog":"NGC","designation":"NGC 3467"},{"catalog":"PGC","designation":"PGC 32903"},{"catalog":"SDSS","designation":"SDSS J105644.07+094532.0"},{"catalog":"SDSS","designation":"SDSS J105644.07+094532.1"},{"catalog":"UGC","designation":"UGC 6045"}],"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.
