Question

The Milky Way Galaxy is about 25 million times larger in diameter than the planetary region of our solar system. If you represent out solar system with a poker chip (diameter about 1.5 inches), how big a disk would you need to represent out galaxy?

Answer 1

`37.5* 10^6\ inches\ or\ 591.85606\ mi`

Step-by-step explanation:

`d_s` = Diameter of the solar system

`d_m` = Diameter of the Milky way =
`25* 10^6* d_s`

Here
`d_s=1.5\ inches`

Diameter of the Milky way would be

`d_m=25* 10^6* 1.5\\\Rightarrow d_m=37.5* 10^6\ inches`

The size of the disk which represents the galaxy is

`37.5* 10^6\ inches=(37.5* 10^6)/(63360)=591.85606\ mi`
