Question

Which is always true about the distance of a planet from the sun? the farther from the sun, the shorter a planet’s revolution. the farther from the sun, the longer a planet’s revolution. the farther from the sun, the shorter a planet’s rotation. the farther from the sun, the longer a planet’s rotation.

Answer 1

The farther from the Sun, the longer a planet's revolution.

Answer 2

Answer:The correct answer is : 'The farther from the sun, the longer a planet’s revolution'.

Explanation:

According to Kepler's third law: 'The square of the orbital period of the planet is directly proportional to the cube of the semi major axis of its orbit'.

$T^2\propto a^3$

From the the above relation we can conclude that, farther the planet from the Sun more time it will take to complete its  revolution.
