A comet orbits the sun is highly elliptical orbit. Does a comet has a constant. kinetic energy

A comet orbits the sun in a highly elliptical orbit. Does the comet have a constant (a) linear speed, (b) angular speed, (c) angular momentum, (d) kinetic energy, (e) potential energy, (f) total energy throughout its orbit? Neglect any mass loss of the comet when it comes very close to the Sun.

When a comet orbits the sun in highly elliptical orbit does a comet have a constant linear velocity?

For a planet moving around the Sun in an elliptical orbit of semimajor and semiminor axes a and b respectively and Time period T. For this situation which one of the following statements is correct?

A planet moving along an elliptical orbit is closest to the Sun at distance r_(1) and farthest away at a distance of r_(2) . If v_(1) and v_(2) are linear speeds at these points respectively. Then the ratio (v_1)/(v_2) is
