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-1049","name":"IC 1049","class":"spiral_galaxy_sa","category":"galaxy","object_type":"Spiral galaxy Sa","mag":14.7,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":320765759.5586155,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":219.888,"dec_deg":62.002944444444445,"epoch_ra_deg":220.055155,"epoch_dec_deg":61.886907,"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":"1889","featured":false,"url":"https://spacecatalog.org/object/ic-1049","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.7,"h_mag":11.2,"j_mag":11.82,"k_mag":10.85,"redshift":0.02235,"hubble_type":"Sa","wikidata_id":"Q3711286","redshift_cmb":0.022577611525524732,"discovered_by":"Lewis A.
