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-1468","name":"NGC 1468","class":"elliptical_galaxy_e_s0","category":"galaxy","object_type":"Elliptical galaxy E-S0","mag":14.99,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":465535136.17044437,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":58.052416666666666,"dec_deg":-6.348944444444444,"epoch_ra_deg":58.38263,"epoch_dec_deg":-6.268245,"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":"Eridanus","discovered":"1881","featured":false,"url":"https://spacecatalog.org/object/ngc-1468","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.99,"h_mag":10.4,"j_mag":11.08,"k_mag":10.08,"redshift":0.03294,"hubble_type":"E-S0","wikidata_id":"Q1043580","redshift_cmb":0.032529356475560434,"discovered_by":"Édouard Stephan","ngc_type_code":"G","uncertainties":{"distance_ly":[23597099.571335446,23597099.571335446]},"major_axis_arcmin":1.22,"minor_axis_arcmin":0.85,"position_angle_deg":140,"surface_brightness":23.99,"radial_velocity_km_s":9713},"designations":[{"catalog":"2MASX","designation":"2MASX J03521258-0620566"},{"catalog":"LEDA","designation":"LEDA 14004"},{"catalog":"MCG","designation":"MCG -01-10-045"},{"catalog":"NGC","designation":"NGC 1468"},{"catalog":"PGC","designation":"PGC 14004"},{"catalog":"SDSS","designation":"SDSS J035212.58-062056.2"}],"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.
