9. Universe All of space and what is found in it. Full of 100 billion galaxies with 100 billion stars each.

11. Super Cluster

12. A collection of galaxies which includes the Local Group (A Cluster). Largest gravitational bound system so far. Ours=Virgo Super Cluster

14. Cluster

15. Ours : - Local Group – The Milky Way Galaxy and its ~50 closest neighbors. A small group of galaxies which are held together by gravity and orbit each other. “Local” means the galaxies are within a region 3 million light years across.

17. Galaxy
