Perihelion shift of Mercury　(クリ）

In a close binary, gravity of main star is acting on companion star. Magnitude of gravity is inversely proportional to square of distance. Therefore, if size of companion star is large, gravity that acting is somewhat larger (even if mass is the same).

Note: Here is a horizontal line. From the right, gravity of main star is acting. On the line, we see three masses. Mass of right and left is m/2 and middle is m (interval is the same). Magnitude of gravity acting will be m<m/2+m/2.
