a) A Kuiper Belt Object orbits the Sun with an average orbital distance of 40 AU. What is its orbital period? Round your answer
denpristay [2]

Answer:

253 years

Explanation:

a = Distance in Astronomical units from the sun = 40 AU

P = Orbital period in years

From Kepler's law we have

P^2=a^3

\Rightarrow P^2=40^3

\Rightarrow P^2=64000

\Rightarrow P=\sqrt{64000}

\Rightarrow P=252.982212813

\Rightarrow P\approx 253\ years

The orbital period of the Kuiper belt object is 253 years.
