How big is the Milky Way?

Question

Not in terms of time though please- in terms of actual distance.

Answer 1

The Milky Way galaxy, our galaxy, is 80-100 thousand light years in diameter, and about 3000 light years thick.



A light year is the distance light travels in one year, so it is a measure of distance and not time. One light year equals about 5,878,499,810,000 miles.

Answer 2

Diameter -- 97,850 light years

9.3^17 kilometers



Thickness (at the central bulge) -- 6,523 ly

6.17^16 kilometers



Earth to center -- 27,724 ly

2.6^17 kilometers

Answer 3

it's 15 million light years thick, and about 100 million light years from spiral to spiral.



the galaxy contains billions of stars.

Answer 4

Our galaxy is about 100,000 light years across. Since one light year is 9.5 trillion km (9,500,000,000,000 km), you multiply 100,000 by 9,500,000,000,000. That equals 950,000,000,000,000,000 km.
