Answer 1

Resposta:

Não sei se entendi muito bem,mas...

The Milky Way is Earth’s home galaxy, the stellar city in which we reside. It’s hefty, containing a few hundred billion stars. And it’s so spacious that, even traveling at the speed of light, it would take more than 100,000 years to get from one side to the other.

NASA estimates the galaxy at 100,000 light-years across. Since one light year is about 9.5 x 1012km, so the diameter of the Milky Way galaxy is about 9.5 x 1017 km in diameter. The thickness of the galaxy ranges depending on how close you are to the center, but it’s tens of thousands of light-years across.
