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":"ngc-7066","name":"NGC 7066","class":"spiral_galaxy_sa","category":"galaxy","object_type":"Spiral galaxy Sa","mag":15.2,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":321.55833333333334,"dec_deg":14.181944444444444,"epoch_ra_deg":321.878408,"epoch_dec_deg":14.297861,"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":"Pegasus","discovered":"1886","featured":false,"url":"https://spacecatalog.org/object/ngc-7066","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.2,"h_mag":10.41,"j_mag":11.19,"k_mag":10.34,"hubble_type":"Sa","wikidata_id":"Q1149377","discovered_by":"Lewis A.
