is circular with radius
, orbit
is elliptical such that the farthest point b is between
and
, and the nearest point a is between
and
. Consider the magnitudes of the velocity of the circular orbit
, the velocity of the comet in the elliptical orbit at the farthest point
, and the velocity of the comet in the elliptical orbit at the nearest point
. Which of the following rankings is correct?
