Determine what the period of revolution of the Earth would be if its distance from the Sun were 4 AU rather than 1 AU. Assume that the mass of the Sun remains the samer

Answer 1

formula

A³=(GMD²)/k²

D_au=(A³k2/(GM))^0.5

D_au=365.25625 days

now A=4A

D_4au=((4A)³k2/(GM))^0.5

D_4au=8D_au

D_4au=2922.05 days
