Why do we see different constellations in the sky at different times of the year?

Answer 1

The fact that we orbit the sun during the course of a year. At any given part of the year, we can't see the stars that are behind the sun. Six months later, we will be able to see those stars.

Answer 2

The Earth is in its orbit around the Sun, so it sees different parts of the sky during the year. The planets, particularly Mars, Jupiter, etc are also going around the Sun. Because of the way that the Earth and these planets coincide with each other, amateur astronomers will usually look forward to a particular season for a certain planet. For example, Jupiter is associated with the summertime, because it moves only slightly faster than background stars. As a result, the time we see it best is in summertime.

Answer 3

Because we tend to do our stargazing at roughly the same time of night whenever we go out, but the constellations move through our clock.

-- Constellations within (your latitude) of the celestial pole are visible at any time on any clear night, all year around.

-- And constellations farther from the pole of the sky are visible at some time of every clear night, for 9 or 10 months of the year.

That is related to Earth's movement around the Sun.
