>If I throw a ball in space, I know my hand exerts force on the ball for it to accelerate, but when I let go, it will keep moving forever in a straight path, with no force acting on it. How is that?
Why did the ball start moving?
You exerted force on it.
What would cause the ball stop moving, or otherwise change it's motion?
An external force acting on it, like someone catching it.
Why does the ball move in a straight line with constant speed?
>No force acting on it.

Depending on the relative altitudes you could observe something through more atmosphere on earth than looking up at stars.
