5. Stars are very big in size. They appear small as they are very far off.	5. Planets are relatively smaller.
6. a star is a huge mass of extremely hot gases and its temperature is very high.	6. A planet is made of rocks and metal and its temperature depends on its distance from the sun.
7. Stars are stationary relative to planets, though a star along with its solar system is moving through million of stars.	7. Planets move round the sun from west to east.
