Neptune is an average distance of 4.5 x 109 km from the Sun. Estimate the length of the Neptunian year using the fact that the Earth is 1.50 x 108 km from the Sun on average.
The length of the Neptunian year using the given data.
Answer to Problem 56P
Solution:
Explanation of Solution
Given:
The average distance between the Sun and Neptune,
The average distance between the Sun and Earth,
Formula Used:
From the Kepler’s third law, for the masses orbiting the Sun
Where,
Calculation:
Considering the period of the Earth as one year, the period of the Neptune ca be calculated as follows:
Conclusion:
Hence, the length of the Neptunian year is obtained as 164.32 Earth years.
