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":"ic-4032","name":"IC 4032","class":"elliptical_galaxy_e_s0","category":"galaxy","object_type":"Elliptical galaxy E-S0","mag":14.68,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":333837218.16559553,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":195.106875,"dec_deg":28.867805555555556,"epoch_ra_deg":195.430441,"epoch_dec_deg":28.723015,"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":"Coma Berenices","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-4032","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.3,"h_mag":11.52,"j_mag":12.29,"k_mag":11.43,"v_mag":14.68,"redshift":0.02258,"hubble_type":"E-S0","wikidata_id":"Q3684167","redshift_cmb":0.023481995683923618,"ngc_type_code":"G","uncertainties":{"distance_ly":[19577219.12208012,19577219.12208012]},"major_axis_arcmin":0.6,"minor_axis_arcmin":0.44,"position_angle_deg":176,"surface_brightness":22.93,"radial_velocity_km_s":6693},"designations":[{"catalog":"2MASX","designation":"2MASX J13002568+2852036"},{"catalog":"IC","designation":"IC 4032"},{"catalog":"LEDA","designation":"LEDA 44756"},{"catalog":"MCG","designation":"MCG +05-31-083"},{"catalog":"PGC","designation":"PGC 44756"},{"catalog":"SDSS","designation":"SDSS J130025.64+285204.1"},{"catalog":"SDSS","designation":"SDSS J130025.65+285204.0"},{"catalog":"SDSS","designation":"SDSS J130025.65+285204.1"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
