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: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.
