A comet is discovered with an orbit that extends from Venus's orbit to Neptune's orbit. Use Kepler's second law to estimate how many times faster the comet is moving when it is closest to the Sun compared to when it is farthest from the Sun. (Hint: The area swept out over a short period of time when the planet is at these two extremes can be approximated by a triangle, and the area of a triangle equals one-half of its base times its height.)
