Question

question 4
where are we located in the milky way?
right where one of the spiral arms joins a group of population ii stars
in the disk, about 2/3 of the way out from the center
right next to the galactic center
in the galactic halo, so we have an unobstructed view of the galactic center

Explanation:

The solar system, where we are located, is in the disk of the Milky - Way galaxy, approximately 2/3 of the way out from the galactic center. This is a well - known fact in astronomy. The other options are incorrect: we are not near the galactic center, not in the halo, and not where a spiral arm joins Population II stars.

Answer:

in the disk, about 2/3 of the way out from the center
