If the sun were the size of a grapefruit how big would the milky way galaxy be?

Well if the sun were the size of a grapefruit we would not have anything in this solar system to compare it to, so lets make the sun the size of a grain of sand (2mm), the milky way would then be the size of our Sun, which is just over 109 the size of earth... however we are basing this off width, being that the Milky Way is disk shaped.

If there is no dark matter in the Milky Way Galaxy what is the best alternative explanation for the observations?
Our understanding of gravity is not correct for galaxy-size scales
What is the size of galaxy NGC 1132?

How much larger is the Andromeda galaxy than earth?
One can not realistically measure the size of a galaxy in terms of the size of the Earth. One usually measures the size of a galaxy in terms of light years. The solar system of which the Earth is just a small speck sits in our local galaxy, the Milky Way which is 100,000 to 120,000 light years across, while the Andromeda galaxy is slightly larger at 220,000 light years in diameter.
If the other galaxy bigger than ours or smaller?
By definition the question is incorrect. There are not only 2 galaxies in our universe, but billions. Each galaxy is a different size and is made up of millions or stars and planets. Our galaxy is called the Milky-Way, and our closest neighbouring galaxy is called the Andromeda galaxy.
The Milky Way Galaxy is a member of the?
It's difficult to be certain; we're inside the Milky Way galaxy, and we've never seen it from the outside. For a long time, astronomers believed that the Milky Way was a classical spiral galaxy, but more complete observations indicates that it is actually a barred spiral galaxy.

Is the milky way galaxy the biggest galaxy discovered?
No. Although the Milky Way is a relatively large galaxy it is nowhere near the largest known. Galaxies dozens of times the size and hundreds of times the mass of the Milky Way have been observed.
How dos your solar system campare to the size of the milky way galaxy?
When compared to the diameter of the Milky Way galaxy,the diameter of our solar system is very nearly zero.
What is the largest galaxy in the local Milky Way?
The ONLY galaxy in the "local milky way" is the Milky Way itself. If you're asking what the largest galaxy in the local group is, the Andromeda Galaxy is the largest by size but the Milky Way may be slightly larger by mass. It's definitely one of those two by any reasonable criterion, though.
What size is the Andromeda galaxy?
About twice the size of the Milky Way, so about 200,000 light-years across, so the Milky Way is 100,000 light-years across.
What is the estimated size of the Milky Way?
Milky Way galaxy range from 100,000 light years up to 120,000 light years.
Which planet in the Milky Way Galaxy is similar to the planet Earths size?
Venus is closest to earths planet size.
If a spiral galaxy is 7.5 billion light-years from Earth and its apparent size is 0.05 arcmin what would its diameter be?

If a spiral galaxy is 5.3 billion light-years from Earth and its apparent size is 0.07 arcmin what would its diameter be?
100,000 light-years (same size as the Milky Way).
If a spiral galaxy is 5 billion light-years from Earth and its apparent size is 0.06 arcmin what would its diameter be?
90,000 light-years (about the same size as the Milky Way).
