Our galaxy, the Milky Way, has a diameter of about 100,000 light-years.
The Andromeda galaxy is approximately 220,000 light-years in diameter. It is the closest spiral galaxy to our Milky Way galaxy.
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.
About 100,000 Light years in diameter and 20,000 Light years in thickness
Major Diameter (arcmin) : 6.5Minor Diameter (arcmin) : 5.6
It's a dwarf galaxy; the diameter is about 6500 light-years (according to information in the Wikipedia article).
Our galaxy has a diameter of about 100,000 light-years; at the speed of light, that would take 100,000 years. Currently there is no technology that allows us to do this.
Our Galaxy The Milky Way is 100,000 light years across the largest section and is 1000 light years deep in thickness
The Milky Way galaxy is approximately 100,000 light-years in diameter.
The M87 is the largest galaxy within the Virgo cluster.It has a diameter of approximately 120,000 light years. The Milky Way Galaxy is a mere 100,000 light years.The Earth for comparison has a diameter of 0.0645 light seconds.
The Andromeda Galaxy is roughly 100,000 light years in diameter.
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.
