The point is it orbited the round Earth and was the starting gun for the space race.

Objects lateral to you (the same distance to center), would be accelerating towards you. Assuming it was gravity pulling you, all objects outwards from you, or in front of you, would appear to be receeding, since you would be accelerating faster than anything further out, but any oject closer to center would be accelerating faster than you. So you would be flanked by blue shift, but ahead and behind would be red shifted.
Actually, it's known that the universe is expanding, however its expansion appears to be accelerating- which should be impossible because of gravity. Therefore, cosmologists have postulated "dark energy" as additional, unobserved energy that is powering this acceleration.
Interesting idea, but what makes you think that? Astronomers report that it is red shifted, which would suggest that it is moving away from us, not towards us.
I can see why this is thought to be true. In actual fact, both the Moon and tides are subject to the same force, which is why they appear to be related. That force is the evaporative power of the Sun. When the Sun shines over a portion of ocean, locally negligible (but very large in total) amounts of water evaporate. The "gap" causes predictable sloshing as the water on the Moon side fills the gap. When the Sun "sets", the water condenses, causing a combination of rainfall and sloshing.
The Earth does not rotate. Why would it?
