How is it slowing down? Is it intentional? I have always been told that in the vacuum of space once something is on a trajectory it will continue indefinitely unless something interrupts it.

The Sun's gravity is always tugging on it.

Huh. So do you know if it will eventually slow all the way down, stop, and start returning towards the sun? Or will some other gravity source capture it before then?

As it moves further away the rate of deceleration decreases. It will never stop even given infinite time.
