Our Milky Way has a supermassive black hole at its nucleus. It is an active radio source. It is probably not a Seyfert galaxy, which is a galaxy of a type characterized by a bright compact core that shows strong infrared emission, though.
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.
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.
The Milky Ways Galactic core. A supermassive black hole at the centre of our Galaxy.
The whole of the galaxy has a diameter of approx 100000 light-years, not just the nucleus! So it is not clear whether the question is about the galaxy or its nucleus.
Gravity on both a galactic and intergalactic scale.
The stars in the spiral arms gradually rotate around the galactic nucleus
The galactic core is the center (not the very center) of the Milky Way Galaxy.

Supermassive black holes tend to hang out in galactic cores. Our own galaxy, the Milky Way, has one at its nucleus.
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.
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 Milky Way galaxy is a flat spiral - one of the commonest galactic forms in the universe.
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.
The Sun is located about 25,000 light years from the galactic core in the Orion Arm of the Milky Way Galaxy.
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.
