Yes it is believed that the Milky Way is getting bigger. A galaxy can only grow if it swallows mass from outside it. Galaxies merge and are absorbed by other galaxies in a process known as Galactic Cannibalism. It is currently believed that a dwarf Galaxy known as the Sagittarius Dwarf is being slowly swallowed by the Milky Way.
The Milky Way galaxy is a flat spiral - one of the commonest galactic forms in the universe.
The closest galaxy that has planets is the Andromeda galaxy. It is the nearest galactic neighbor to the earth. The Milky Way has other planets too.
The Sun is located about 25,000 light years from the galactic core in the Orion Arm of the Milky Way Galaxy.
The galactic rim refers to the outer edge or boundary of a galaxy, such as the Milky Way. It is not visible as a distinct feature in the night sky. The galactic rim is not the same thing as the center of the Milky Way, which is a dense region of stars and dust located towards the middle of the galaxy.
If I understood the question correctly, our galaxy, the Milky Way, is part of the Local Group.
Our solar system is not far from the end of one of the spiral arms of the Milky Way. Our sun is about 26 or 27 thousand light years from the galactic center, and the galaxy is about 70 to 100 thousand light years across. See link for more information.See link for pictorial representation.
Yes. The Andromeda Galaxy, our galactic neighbor, is heading toward the Milky Way and is expected to collide with our own galaxy in about 3 billion years.
