Halley's comet moves i all Which of the following best explains why the comet loses speed in this way? Choose 1 answer: The centripetal force exerted on Halley's comet is smaller than the gravitational force exerted on Halley's comet during this portion of the orbit. As Halley's comet recedes from the sun, the Sun-comet system gains potential energy, and Halley's comet loses kinetic energy. The Sun exerts a torque on Halley's comet during its motion about the sun and decreases the Sun-comet system's angular momentum. A component of the gravitational force on Halley's comet is perpendicular to its direction of motion, causing the comet to lose speed.
