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.
When compared to the diameter of the Milky Way galaxy,the diameter of our solar system is very nearly zero.
The Andromeda galaxy is approximately 220,000 light-years in diameter. It is the closest spiral galaxy to our Milky Way galaxy.
Our galaxy is a barred spiral galaxy. There is a bar of stars, like the diameter of a circle, from which the spirals emanate, so to speak.
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.
Variable, as an ellipse is not a perfect circle.
