Question

if the radius of Earth's orbit is made 1/4 the duration of an year will become ​

Answer 1

Answer:

To solve this problem we can resort to Kepler’s third law of orbital motion and it states that the square of the average orbital period of a planet is proportional to the cube of its average orbital radius such that;

T2∝R3T2∝R3

So here is the math :

Look at the pic now :

the orbital period of the Earth, i.e. a year would decrease to 365/8≈45.6365/8≈45.6 days
