The main disk of the Milky Way Galaxy is about 80,000 to 100,000 light-years in diameter, about 250,000 to 300,000 light-years in circumference, and outside the Galactic core, about 1,000 light-years in thickness. It is composed of 200 to 400 billion stars [1]. As a guide to the relative physical scale of the Milky Way, if the galaxy were reduced to 130 km (80 mi) in diameter, the solar system would be a mere 2 mm (0.08 inches) in width. The Galactic Halo extends out to 250,000 to 400,000 light-years in diameter. As detailed in the Structure section below, new discoveries indicate that the disk extends much farther than previously thought.

Yes, there is. The end to the planetary solar system is after neptune, at the Kuiper Belt. The other definition for the end of the solar system is when all solar winds stop and interstellar space begins. This area is called the heliopause.
There is actually 4 probes to exit the solar system into interstellar space, Voyagers 1 & 2, Pioneers 10 & 11.

In time, over billions of years, the sun will use up all its nuclear fuel and die out.
If you're taling about the size-limits of the solar system, the gravitional force of the sun goes on to infinite distance, just getting very weak and declining with the square of the distance.
You could say the size of the solar system is the radius of the orbit of the outer-most object orbiting the sun (the junk near pluto)

There is an end to the planets orbiting the sun but but the sun has a hold on everything else in the universe as does everything. Its all bcause of gravity. It may not amount to hardly anything but its still there. In a few billion years the milky way galaxy is going to crash into the andromeda galaxy creating a superdense and supermassive black hole.

Yes! It could happen with this solar system when our sun dies, or we get sucked into a black hole, or when another solar system collied with our solar system.

Yes it is called the Heliopause. The point where the sun's influence becomes nothing against the interstellar medium.

Yes, it's called the heliopause. Our probes just recently went through the heliopause actually.

Yes, the point at which it's gravity no longer affects objects.

a physical end or a temporal end? in both cases, the answer is yes.

I don´t believe it exists.
