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-2469","name":"IC 2469","class":"barred_spiral_galaxy_sbab","category":"galaxy","object_type":"Barred spiral galaxy SBab","mag":11.09,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":91692009.9398366,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":140.75441666666666,"dec_deg":-32.449749999999995,"epoch_ra_deg":141.03718,"epoch_dec_deg":-32.564271,"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":"Pyxis","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-2469","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":12.14,"h_mag":7.55,"j_mag":8.37,"k_mag":7.33,"v_mag":11.09,"redshift":0.005527,"hubble_type":"SBab","wikidata_id":"Q3690723","redshift_cmb":0.006531721451306316,"ngc_type_code":"G","uncertainties":{"distance_ly":[14525214.349798033,14525214.349798033]},"major_axis_arcmin":5.79,"minor_axis_arcmin":1.17,"position_angle_deg":37,"surface_brightness":23.73,"radial_velocity_km_s":1652},"designations":[{"catalog":"2MASX","designation":"2MASX J09230105-3226591"},{"catalog":"ESO","designation":"ESO 433-017"},{"catalog":"ESO","designation":"ESO 433-17"},{"catalog":"IC","designation":"IC 2469"},{"catalog":"IRAS","designation":"IRAS 09208-3214"},{"catalog":"LEDA","designation":"LEDA 26561"},{"catalog":"MCG","designation":"MCG -05-22-008"},{"catalog":"PGC","designation":"PGC 26561"},{"catalog":"UGCA","designation":"UGCA 163"}],"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.
