How big is the Milky Way Galaxy?

Answer 1

The milky way is approximately 100,000 light years across and 1,000 ly thick at the thickest part.

1 mile = 63,360 inches

1 ly = 9.461×1015 miles.

So 1,000 ly = 9.461 x 1018 miles = 5.99x1023 inches thick.

100,000 ly = 9.461 x 1020 miles = 5.99x1025 inches across.
