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-7732","name":"NGC 7732","class":"spiral_galaxy_scd","category":"galaxy","object_type":"Spiral galaxy Scd","mag":13.89,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":128460717.80465284,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":355.391125,"dec_deg":3.7249444444444446,"epoch_ra_deg":355.734256,"epoch_dec_deg":3.873809,"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":"Pisces","discovered":"1864","featured":false,"url":"https://spacecatalog.org/object/ngc-7732","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.33,"h_mag":11.02,"j_mag":12.35,"k_mag":10.79,"v_mag":13.89,"redshift":0.010367,"hubble_type":"Scd","wikidata_id":"Q1168982","redshift_cmb":0.009133011573395411,"discovered_by":"Albert Marth","ngc_type_code":"G","uncertainties":{"distance_ly":[14996511.417679867,14996511.417679867]},"major_axis_arcmin":1.49,"minor_axis_arcmin":0.47,"position_angle_deg":92,"surface_brightness":22.96,"radial_velocity_km_s":3092},"designations":[{"catalog":"2MASX","designation":"2MASX J23413385+0343298"},{"catalog":"IRAS","designation":"IRAS 23390+0326"},{"catalog":"IRAS","designation":"IRAS F23390+0327"},{"catalog":"LEDA","designation":"LEDA 72131"},{"catalog":"MCG","designation":"MCG +00-60-035"},{"catalog":"NGC","designation":"NGC 7732"},{"catalog":"PGC","designation":"PGC 72131"},{"catalog":"UGC","designation":"UGC 12738"}],"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.
