Final answer:
The diameter of the Milky Way is 100,000 light-years, while the distance to Andromeda is 2.5 million light-years, making Andromeda 25 times the diameter of our galaxy away.
Step-by-step explanation:
The diameter of the Milky Way Galaxy is 100,000 light-years, and the distance to the Andromeda Galaxy, our closest large galactic neighbor, is approximately 2.5 million light-years. If we were to divide the distance to Andromeda by the size of the Milky Way (2,500,000 light-years ÷ 100,000 light-years), we'd find that Andromeda is about 25 times the diameter of our galaxy away from us. This calculation helps us understand the scale of distance within our local group of galaxies and emphasizes the vastness of intergalactic space.
