    Solar sys. Is moving at speed of 800k km/hr then how we see stars at same position
    The entire Solar system is moving at a speed of 800000 km per hour, then how come we see the stars, which are out of solar system, at same position daily. If one object is moving and other not with it then the position must be seen changed.

    I do not know of any object that is not moving? What object do you believe is not moving.

    If two cars are moving down the road, both at 50 mph, do they appear to be moving to each other?

    If you and your friend are in a car moving 80 mph, why do you appear to stay in the same place, relative to the car, to your friend.

    The entire universe is expanding, so our solar system is just a tiny tiny spot in it all.
    The stars you see actually are in different positions relative to you and everything else, but you can't see it day to day.
    A computerized telescope can.

    All stars are moving relative to each other. It has nothing to do with the expansion of the universe (the effects of cosmic expansion can only be noticed at very great distances - on the order of millions of light years, which is way beyond our local galaxy group). The stars you see at night are all orbiting about the center of the Milky Way at almost the same speed, but there are differences that can be measured. However, given that all stars (other than our own sun) are all at least 3 light years away, it is very difficult to perceive the movement. Nevertheless over time spans of hundreds or thousands of years this movement leads to changes in the relative positions of stars in the constellations. Here's an interesting video on the subject: The Proper Motion of the Stars of Ursa Major

    Think of driving along and watching telephone poles whiz by. Now look at a mountain that is 50 miles away. How fast does it seem to move? Now, as ebaines noted, a star is at least 3 light years away-18 TRILLION miles! It would never seem to move but it does. We just aren't here long enough to see it.
