Remark:
Min II 5.76; Min II - Min I = 0.418P (1963).
There are periodic terms in the elements:
+0.8916d*sin(38.8deg + 0.0082deg*E) -
0.0796d*sin(77.6deg + 0.0164deg*E) + 0.0088d*cos(26.4deg +
0.0246deg*E); Min II = 2441262.266 + 12.425612d*E -
0.8916d*sin(38.8deg + 0.0082deg*E) - 0.0796d*sin(77.6deg +
0.164deg*E) - 0.0088d cos (26.4deg + 0.0246deg*E).
Apsidal motion is possible with P = 1490 years.
