Estimate what is its speed when it is farthest from the sun

Reference no: EM13564737

Halley's comet moves about the Sunin an elliptical orbit, with its closest approach to the Sun being0.59 A.U. and its greatest distance being 35 A.U. (1 A.U. =Earth-Sun distance). If the comet's speed at closest approach is45 km/s, what is its speed when it isfarthest from the Sun? You may neglect any change in the comet'smass and assume that its angular momentum about the Sun is conserved.
