Comets move around the sun in very elliptical orbits. At its closest approach, in 1986 Comet Halley was 8.79 x 10' km from the sun and moving with a speed of 54.6 km/s. What was the comet's speed when it crossed Neptune's orbit in 2006? (Neptune: mean distance from the sun 4.50 x 102 m; Mass 1.03 x 102 kg)
