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-3232","name":"NGC 3232","class":"intermediate_spiral_galaxy_saba","category":"galaxy","object_type":"Intermediate spiral galaxy SABa","mag":15.5,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":311308047.2309527,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":156.10095833333335,"dec_deg":28.026138888888887,"epoch_ra_deg":156.477985,"epoch_dec_deg":27.890214,"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 Minor","discovered":"1861","featured":false,"url":"https://spacecatalog.org/object/ngc-3232","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.5,"redshift":0.020914,"hubble_type":"SABa","wikidata_id":"Q1103713","redshift_cmb":0.021922519206430513,"discovered_by":"Heinrich Louis d'Arrest","ngc_type_code":"G","uncertainties":{"distance_ly":[18952925.76489503,18952925.76489503]},"major_axis_arcmin":0.85,"minor_axis_arcmin":0.69,"position_angle_deg":57,"surface_brightness":23.7,"radial_velocity_km_s":6204},"designations":[{"catalog":"LEDA","designation":"LEDA 30508"},{"catalog":"MCG","designation":"MCG +05-25-004"},{"catalog":"NGC","designation":"NGC 3232"},{"catalog":"PGC","designation":"PGC 30508"},{"catalog":"SDSS","designation":"SDSS J102424.22+280134.0"},{"catalog":"SDSS","designation":"SDSS J102424.22+280134.1"},{"catalog":"SDSS","designation":"SDSS J102424.23+280134.1"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
