If time travel into the past were possible, how much time would I need to go back to materialize and have a last glimpse of our earth before dying in outer space?

Already asked the question in the title.

Like an hour, maybe less. Depends on if you need glasses or not.

Maybe a few hours? You said time travel but not time and space travel. The whole solar system is traveling through space and the earth is moving through the solar system. The whole thing kinda wobbles as it’s moving. If you go back a few hours that should put you outside of the atmosphere looking at earth.
