Answer :
Final answer:
Neptune takes about 164 years to complete one orbit around the sun, which is significantly longer than Earth's 1-year period. This long orbit is due to Neptune's considerable distance from the sun. Understanding this duration helps illustrate the characteristics of outer planets in our solar system.
Explanation:
Orbital Period of Neptune
Neptune completes its orbit around the sun in approximately 164 years. This long orbital period is due to its significant distance from the sun, which is about 4.5 billion kilometers or 2.8 billion miles, making it the farthest planet in our solar system. The long duration is a characteristic of outer planets as they travel in extended orbits that require more time to complete one full revolution around the sun.
Comparison with Other Distances
For context, Earth's orbital period is about 1 year, while Neptune's orbital period of 164 years is substantially longer due to its increased distance from the sun:
- Earth: 1 year
- Neptune: 164 years
