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-1360","name":"NGC 1360","class":"planetary_nebula","category":"nebula","object_type":"Planetary nebula","mag":9.4,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":1144.8088857857695,"distance_method":"Statistical distance scale for planetary nebulae (Stanghellini+ 2008)","ra_deg":53.31104166666666,"dec_deg":-25.87172222222222,"epoch_ra_deg":53.5978,"epoch_dec_deg":-25.780804,"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":"Fornax","discovered":"1868","featured":false,"url":"https://spacecatalog.org/object/ngc-1360","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":9.6,"h_mag":12.29,"j_mag":12.08,"k_mag":12.37,"v_mag":9.4,"redshift":0.00036,"wikidata_id":"Q899940","discovered_by":"Lewis A.
