Question

A comet (see the figure below) approaches the Sun to within 0.570 AU, and its orbital period is 79.6 yr. (AU is the symbol for astronomical unit, where 1 AU = 1.50 !! 10^11 m is the mean Earth-Sun distance.) How far from the Sun will the comet travel before it starts its return journey? AU Sun 0.570 AU x 2a (Orbit is not drawn to scale.)

Step 1

67 \times 10^{-11} \, \text{m}^3 \, \text{kg}^{-1} \, \text{s}^{-2}$ - Mass of the Sun, M = $1.989 \times 10^{30} \, \text{kg}$ - Time period of the comet, T = 79.6 years = $2.514 \times 10^9$ seconds - $\pi \approx 3.14$ Using Kepler's third law: $a^3 = \frac{G Show more…
