Question

HURRY FOR 100 POINTS AND BRAINLIEST!!!!!!!!!!!

Answer 1

14) Star clusters are stars that group together. Star clusters are held together due to a mutual gravitational attraction. Star clusters range from 10 million years old to 100 million years old. Astronomers categorize star clusters based on age, brightness, what types of stars make up the group, and how large the group is.
15) Open clusters are made up of a couple thousand stars that formed in the same molecular cloud and open clusters have loose gravitational pulls thus causing the stars to eventually disperse and then form field stars. 
16) The sun is located in the Hyades Cluster where our entire solar system is located. 
17) Globular clusters are different from open clusters because they contain more stars, have a stronger gravitational pull, and are older than open clusters.
18) Two star clusters visible to the naked eye are Messier 13 and Omega Centauri. 

Answer 2

Hi!

14. Star clusters are held together by gravity. It really depends how old a star in the cluster is - it could be just born, or could have been born hundreds of billions of years ago. Astronomers categorize them by different colors, temperatures, sizes, brightness, etc. 

15. Open clusters eventually disperse to form field stars. 

16. Our sun is not part of a cluster (although it used to be). 

17. Globular clusters are found in the ring of a galaxy and usually contain more stars and are much older than the open clusters. 

18. Omega Centuari and M13. 

Hope this helps!
