when will the earth go in retrograde motion?

Question

astronomical aspect please

Answer 1

There is no reason to think the earth will ever spin in a direction opposite of its current spin.

It is true that the earth's spin is gradually slowing (which means there's a slight "east-to-west" push that's slowing it down). But that doesn't mean that it will eventually stop and reverse direction.

The "east-to-west' push is a sort of "braking" force which is cause by ocean tides as they try to stay underneath the moon. But if the earth ever slows to the point where it always shows the same face to the moon, then the "braking" force stops acting.

Answer 2

retrograde motion is used to refer to "other" planets when observed from the Earth. They appear to move backwards with respect to the stars.

So unless you are standing somewhere else other than the Earth you will never see the Earth in retrograde motion.

Answer 3

What planet are you on to make the observation?

Answer 4

Never.
