[LOTR]What's beyond middle Earth?

They work on a Gregorian calendar as the date October 24th is said in the fellowship meaning the Earth is at the same distance from the the sun and revolving at the same speed.

Middle Earth is more so the continent that everything takes place on. The name of the world itself is Arda. BUT, Arda is also earth.
