It's due to the shifting of the Earth's axis throughout the year with relation to the rest of the galaxy.
As you probably know, in the summer time, the north pole tilts toward the Sun, and away in winter, therefore slightly changing our view of the sky.
Also, from our point of view, as the earth rotates around the sun, it passes in front of different parts of the sky, effectively washing out the stars there with daylight.
Also, the stars we can see depend on what latitude we're on--that is, how far north or south. People in the southern hemisphere have a whole different view of the sky with different constellations, such as the Coalsack Nebula and the Southern Cross, but they can't see the Plough (or Big Dipper, or Ursa Major)

Because the Earth is moving around the Sun. Depending on what part of the Earth's orbit, and where you are located in the world, you will see different stars at night throughout the year. The link below should help you understand better.

Because of the earth's relative position to the sun at different times of the year, which is due to the fact that the earth's axis is tilted, thus you see the sky from different "angles" in summer vs. winter, in conjunction with the earth orbiting around the sun.

the earth has a slight tilt to its axis, which points toward, or away from the sun at different times of year. This causes the seasons, and allows us to view different stars as well.

Because the earth is in a different position in the solar system. We all get a free trip around the sun each year!

the earth orbits the sun which creates the seasons. the stars and planets are stationary. therefore, as the earth spins on it's axis daily, and rotates the sun yearly, we see the planets appearing to be in different locations.

Because the 'night' side of the planet faces in different directions at different times of the year due to our orbiting around the Sun.

it's the way the earth rotates around the sun look at our solar system and follow the track it's kinda obvious why we would see differant stars at differant times , it's becuase we're in a differant place

well they don't just appear. They are always there. It is just at different times of the year the earth is in the correct position for you to see them.

Because the earth is tilting back and forth on its vertical axis. This is what causes winter and summer. Our angle of looking at the universe is therefore different.
