Suppose there existed a planet that went around the sun twice as fast as the earth. What would be its orbital size as compared to that of the earth?

View answer and explanation

Correct option: A

{0 . 6 3} \mathrm{~AU}

Option A (

{0 . 6 3} \mathrm{~AU}

) is correct because it is calculated using Kepler's Third Law, relating the orbital period and orbital size.
