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-1211","name":"IC 1211","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":13.76,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":265528001.45446166,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":244.21658333333335,"dec_deg":53.00602777777778,"epoch_ra_deg":244.383357,"epoch_dec_deg":52.939128,"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":"Draco","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-1211","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.76,"h_mag":9.94,"j_mag":10.64,"k_mag":9.68,"redshift":0.018686,"hubble_type":"E","wikidata_id":"Q3710889","redshift_cmb":0.01874274750353444,"ngc_type_code":"G","uncertainties":{"distance_ly":[17759690.476578183,17759690.476578183]},"major_axis_arcmin":1.34,"minor_axis_arcmin":1.25,"position_angle_deg":65,"surface_brightness":23.34,"radial_velocity_km_s":5550},"designations":[{"catalog":"2MASX","designation":"2MASX J16165191+5300213"},{"catalog":"IC","designation":"IC 1211"},{"catalog":"LEDA","designation":"LEDA 57707"},{"catalog":"MCG","designation":"MCG +09-27-009"},{"catalog":"PGC","designation":"PGC 57707"},{"catalog":"SDSS","designation":"SDSS J161651.97+530021.6"},{"catalog":"UGC","designation":"UGC 10314"}],"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.
