Question
Why do the stars and the constellations in the sky appear to change positions throughout the night and throughout the year?(1 point)
Responses

The Earth’s tilt changes its position relative to the stars and constellations as the Earth rotates and orbits.

The location angle of the Earth's tilt relative to the stars and constellations remains the same throughout the year.

The stars and constellation have tilted and are also moving in space.

The Earth’s tilt changes its position relative to the stars and constellations only because the Earth rotates around its axis.

Answer 1

The first response is correct:

The apparent motion is caused by the Earth's rotation (making the stars move across the sky each night) and the Earth's orbit around the Sun (so different constellations are visible at different times of year). The Earth's axial tilt also affects which constellations are visible in different seasons.
