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-1219","name":"IC 1219","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0","mag":15.13,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":504194891.5747388,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":246.114375,"dec_deg":19.48258333333333,"epoch_ra_deg":246.410473,"epoch_dec_deg":19.420301,"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":"Hercules","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-1219","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.13,"h_mag":10.88,"j_mag":11.59,"k_mag":10.44,"redshift":0.03497,"hubble_type":"S0","wikidata_id":"Q3710838","redshift_cmb":0.03516341019765923,"ngc_type_code":"G","uncertainties":{"distance_ly":[24868698.865737945,24868698.865737945]},"major_axis_arcmin":1.31,"minor_axis_arcmin":0.52,"position_angle_deg":122,"surface_brightness":24.34,"radial_velocity_km_s":10301},"designations":[{"catalog":"2MASX","designation":"2MASX J16242743+1928573"},{"catalog":"IC","designation":"IC 1219"},{"catalog":"IRAS","designation":"IRAS 16222+1936"},{"catalog":"LEDA","designation":"LEDA 58037"},{"catalog":"MCG","designation":"MCG +03-42-005"},{"catalog":"PGC","designation":"PGC 58037"},{"catalog":"SDSS","designation":"SDSS J162427.44+192857.2"},{"catalog":"UGC","designation":"UGC 10371"}],"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.
