In the figure (I) shown
below, A is a object representing
earth and S is a small object representing a
satellite which is rotating around A in an exact
circular orbit. Now in figure (II) let there be
an another object B that appears near A. Let B be
similar to moon. The circular orbit of S will
take the shape as shown in Fig (II). Here the
orbit of satellite is not passing through the
line joining the centre of A and B.
But, if the path of S is
such that it exactly passes through the line
joining the centre of A and B, the orbit will
get distorted as shown in fig (III). The object
S will get sudden jerk of push towards B when it
will be crossing at M. The same effect of
comparatively smaller magnitude will be observed
at the location L.
These disturbances at L and
M for S will be caused because the push rays
which are pushing it towards A are suddenly
blocked by B when S is passing between the area
of their common tangents.
