Because the Earth and all the planets move in orbits round the Sun, while the stars appear to be fixed if we disregard the Earth's daily rotation.
All the planets (Greek for "wanderer") change position with respect to the stars. The reason is that they orbit the sun, as does the earth.
Planets are in a slightly different position each night with respect to the stars. The word planet is derived from a word meaning wanderer.
Because the Earth is rotating :D
Day and night, the planets constantly orbit the sun. This makes the planetary positions appear to change each night with respect to the background stars from the perspective of earth. So the positions do not change only at night, it is just at night we can see the positions have changed a little bit more.
They change position against the background of the distant stars because they are much closer to us, and they are orbiting around the sun, as are we.
Adjective Of or with respect to the stars (i.e., the fixed stars, not the sun or planets).
