Question

Sort the descriptions of open clusters and globular clusters into open clusters or globular clusters

Answer 1

Answer:

open clusters are  A.no more than a few thousand stars, B.disorganized, F loose

globular clusters are C.tightly packed, D.more than a million stars, E.made of older stars

Explanation:

Globular clusters are old clusters of stars that have remained in a gravitationally bound system. These clusters are usually roughly spherical and can contain anywhere from a few thousand to a million stars. Globular clusters are found in our galaxy’s spherical halo, so they are distributed above, below, and level with the plane of our flat, disk-shaped Milky Way.

Open clusters are much younger and smaller than globular clusters. They are the recent birthplaces of new stars, which form out of clouds of dust and gas, and contain only hundreds or thousands of stars. Though the stars in an open cluster formed together out of the same material, they do not remain gravitationally bound over time and spread out, scattering their stars far and wide. Because they are not gravitationally bound, these clusters can have random and irregular shapes. They are located in the plane of our galaxy, along the spiral arms where the gas and dust in the Milky Way
