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-2211","name":"IC 2211","class":"barred_spiral_galaxy_sba","category":"galaxy","object_type":"Barred spiral galaxy SBa","mag":14.56,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":261673932.26159742,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":119.44025,"dec_deg":32.55811111111111,"epoch_ra_deg":119.867778,"epoch_dec_deg":32.486177,"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":"Gemini","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-2211","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.56,"h_mag":10.71,"j_mag":11.46,"k_mag":10.47,"redshift":0.01786,"hubble_type":"SBa","wikidata_id":"Q3692104","redshift_cmb":0.018474382599858563,"ngc_type_code":"G","uncertainties":{"distance_ly":[17664340.205873083,17664340.205873083]},"major_axis_arcmin":0.82,"minor_axis_arcmin":0.45,"position_angle_deg":139,"surface_brightness":22.68,"radial_velocity_km_s":5306},"designations":[{"catalog":"2MASX","designation":"2MASX J07574566+3233295"},{"catalog":"IC","designation":"IC 2211"},{"catalog":"IRAS","designation":"IRAS 07546+3241"},{"catalog":"IRAS","designation":"IRAS F07545+3241"},{"catalog":"LEDA","designation":"LEDA 22314"},{"catalog":"MCG","designation":"MCG +05-19-023"},{"catalog":"PGC","designation":"PGC 22314"},{"catalog":"SDSS","designation":"SDSS J075745.65+323329.2"},{"catalog":"SDSS","designation":"SDSS J075745.66+323329.1"},{"catalog":"SDSS","designation":"SDSS J075745.66+323329.2"},{"catalog":"UGC","designation":"UGC 4119"}],"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.
