HINT: Can you find a relationship between the centripetal acceleration and the period of rotation?

okay thanks for the hint but i didnt really get the answer. taking the formula

Acc = radius x omega^2
omega = 2pie (1orbit) / time

i took time to be 365.25 x 24 x 60 x 60 to get s.

My results were wrong :(

Perhaps if you showed us your calculations, we could point out where you're going wrong.
