The patterns of stars in the sky stay the same, although they appear to move across the sky nightly, and different stars can be seen in different seasons. Telescopes magnify the appearance of some distant objects in the sky, including the moon and the planets. The number of stars that can be seen through telescopes is dramatically greater than can be seen by the unaided eye.
Planets change their positions against the background of stars.
The earth is one of several planets that orbit the sun, and the moon orbits around the earth. Stars are like the sun, some being smaller and some larger, but so far away that they look like points of light. Like all planets and stars, the earth is approximately spherical in shape. To people on earth, this turning of the planet makes it seem as though the sun, moon, planets, and stars are orbiting the earth once a day. Clouds and fog are made of tiny droplets of water.
