Comet Halley approaches the Sun to within 0.570 AU and its period is 75.6 years. How far from the Sun will this comet travel before it starts to return journey. Assume mass of Halley's comet is much smaller than the mass of the Sun.
[Given : 1 AU $= 1.5 \times 10^{11}$ m, $G= 6.63\times10^{-11}$ N.m\(^2\) /kg\(^2\), Mass of Sun=\( 1.99\times10^{30}\) kg ].
