Question

The planet Neptune orbits the Sun. Its orbital radius is 30.130.1 astronomical units (\text{AU})(AU).

Assuming Neptune's orbit is circular, what is the distance it travels in a single orbit around the Sun?

Answer 1

60.2π

Explanation:

Answer 2

Answer: 189.028 AU.

Explanation:

Given: The radius of the orbit = 30.1 AU

Since, the orbit is circular in shape, then the distance traveled by Neptune is given by:-

`\text{Circumference=}2\pi r\\\\\Rightarrow\ \text{Circumference=}2(3.14)*(30.1)\\\\\Rightarrow\ \text{Circumference=}=189.028\text{ AU}`

Hence, the distance traveled by Neptune in a single orbit around the Sun = 189.028 AU.
