These two views show the position of Halley's comet and six planets on Jan. 7, 1984, when the three images of the accompanying release (P-27304 B) were taken. At that time, Halley was about 800 million miles from the sun, traveling at an 18-degree tilt with respect to the plane of the solar system. Halley is currently inbound toward the sun and moves in a retrograde, or clockwise, direction as seen from the north, above the solar system: by comparison, the planets move in the other direction. Halley will come closest to the sun on Feb. 9, 1986. During its passage through the inner solar system, the comet will be observed by meml ers of the International Halley Watch, which is coordinating worldwide ground-based studies. Lead centers are at JPL and the University of Erlangen-Nurnberg in Bamberg, West Germany.
