Give reason.We  see  the  planets  and  stars  moving  from  the  east  to  the west.MSCERT Class 8th General Science Ch1 Stars and our Solar System

Answer 1

because our earth rotate from west to east, so we see the planets and stars moving from the east to the 
west.

Answer 2

The celestial objects like planets and stars appear to move across the sky from east to west because :
--> Earth move on its own axis from west to east.
---> It takes earth nearly 24 hours to complete one rotation  on its own axis from west to east.
---> But to our eyes it appears that our earth is at rest and the various objects in space are moving from east to west.
