One day is defined to be about 24 hours. Why do you think people say winter days are shorter than summer days?

• Because the daylight hours are shorter.

A group of stars is called what?

• constellation

• schools

Why do the stars appear to move across the sky every night?

• Because of earths tilt

• Because the Earth rotates once every 24 hours.

Earth's place in its orbit affects which stars can be seen during different/the same seasons. The location of stars in the night changes as Earth moves along its orbit. During the year, you will be able to see all the stars visible from one specific place on Earth. On a given day, you will only be able to see the stars that are in the opposite direction of the sun. The star seen from the Northern Hemisphere may be different from the Stars scene from the southern hemisphere. If you are on the North or South Pole, the Stars will appear to rotate around a point directly above your head because of Earth's rotation. The sky seen from the North Pole is completely different then the sky seen from the South Pole. As you move from the North Pole to the South Pole the sky will change/stay the same. The sky seen by someone in Florida may have some of the same stars in the sky seen by someone in Brazil, but the whole pattern of the Stars seen is/ is not the same.
