Astronomy The study of everything beyond Earth!

Order of the Universe  

From Largest To Smallest

Universe  All

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

Super Cluster 

 

Cluster of clusters of galaxies, which include the local group. Largest gravitational bound system so far. Ours=Local Super Cluster

Cluster 

 

A small group of galaxies. They are held together by gravity and orbit each other. Ours = Local Group Milky Way Galaxy and its 34 closest neighbors. “Local” means the galaxies are within a region 3 million light years across.

Galaxy A

vast collection of dust , gas, and stars held together by gravity.  Ours = Milky Way

Sun’s Neighbors  The

sun and its 20 closest neighboring stars.  Some of Ours = Proxima Centauri; Aplha Centauri

Solar System A group of satellites revolving around a star.  Ours = The sun and its collection of 8 planets. 

Star 



A hot, bubbling, glowing ball of gas. It radiates a huge amount of energy in forms of light and heat. Ours = The Sun

Planet  

An object that revolves around a star. Ours = The Earth

Natural Satellite  An

object that revolves around a planet  Ours = The Moon; Diana
