do all the stars in the sky moves?explain
Stars are like our sun. They are stationary and do not move, but planets and moons do move. They orbit stars. Anyhow, why it looks like that stars move? As you watch the sky in early night, it looks different than later at night. Stars change their position as the night goes on. They start rising in early evening, reach the highest position after midnight and finally go below the horizon in early morning. Only the circumpolar stars do not go below horizon, but also their position in our night sky changes.
The obvious reason for this phenomenon is that our planet move. The Earth circulates, and that’s why we see the sun and other stars changing their location in the sky. Because of this we have days and night. In addition to circulation, our planet is on move. We orbit the Sun and because of this we have winters and summers. Based on our continuous move we see the stars changing their location in our night sky. How could you see this happening? Here’s the tip for noticing how the stars move in the night sky.
We can easily see how the stars change their position in night sky. You need to observe the sky at least during two nights in order to notice the move
all tyhe stars r moving. As the universe is expanding, the galaxies are moving and stars are also moving. and another reason for that is that,the galaxies are black holes so all the stars are revolving around it.sun take about 230 billion years to complete 1 round around milky way.
Now,all the stars rotate and revolve around their respective galaxies ; and due to earths rotation they appear to move from east to west whereas there direction of movement could be actually from anywhere to anywhere ,the only reason we are not able to see there motion (leaving beside the rotation of earth) is the distance between them and the Earth i,e, it is the same like when we are inside a car and moving at high speed then to faraway trees appear to be stationary.(i did not mention sky because the clouds are huge and they also keep moving due to winds.)
