Agroup of older stars that cluster together in a spherical shape and can contain up to one million stars per cluster is called:

a. a globular cluster
b. open clusters
c. spherical clusters
d. accretion

The answer would be letter A. globular cluster. This group of very old stars that are clustered together in a spherical in shape and can contain from 10,000 to several million is called a globular cluster. In our galaxy, there are 150 globular clusters.

Used to water and cool climates, probably not thick coated or fluffy. they most likely have thin coats and have to survive to find food. sorry if this wasn't the answer you were looking for..: )
