A point where the center does not have gravitational pull... once things stop orbiting thats it for the galaxy
The halo of a galaxy is a large, diffuse region of stars and dark matter that surrounds the main, visible disk of the galaxy. It can extend far beyond the visible boundaries of the galaxy and plays a key role in the gravitational dynamics of the galaxy, as well as in shaping its overall structure.
The diameter of the Milky Way galaxy is about 100,000 light-years. If the Sun and Earth were at the edge of the disk, we would still be within the galaxy's boundaries, so the diameter would remain around 100,000 light-years.
Our galaxy is a barred spiral galaxy.
The Andromeda Galaxy is a spiral galaxy.
Our galaxy is a spiral galaxy because it is spiral in shape.
Not counting the Magellanic Clouds (which are minielliptical galaxies orbiting our galaxy), the Andromeda galaxy is the galaxy nearest to our galaxy.

No, a tadpole galaxy is not a type of peculiar galaxy. It is a barred spiral galaxy.

No. The Milky Way is believed to be a barred spiral galaxy.
