Why do constellations change shape?
The actual boundaries of the constellations do not change, but because all stars are moving, the shapes appear to change. e.g. Ursa Major (the Big Dipper) will be a different shape in 100,000 years as the stars that comprise it are all moving relative to each other.
Why do all the constellations appear to be moving?
Everything in the sky appears to be moving because Earth is rotating. BUT - also, Earth is orbiting the Sun, and the Sun and all the planets are rotating in an arm of the Milky Way Galaxy, which is also moving through the Universe....

Why do stars in constellations move?
Stars in constellations appear to move across the sky because of the Earth's rotation on its axis. As the Earth rotates, different stars come into view while others disappear over the horizon. This creates the illusion of movement within constellations.
Do all constellations rise and set?
Yes - EVERYTHING in the sky rises and sets, because Earth rotates on it's axis.
Why does the number of circumpolar constellations depend on latitude?
Circumpolar Constellations are those that appear to circle the North Star, Polaris. Polaris' place in the sky changes based on the viewers latitude. The closer you get to the North Pole, the higher in the sky Polaris appears, and therefore the more constellations appear to spin around Polaris.
Why does the moon appear to be moving very quickly?
because it is smaller and when you look up at it it seems to be moving faster than all of the other planets!!
Why does the number of circumpolar constellations depend on the latitude of the observer?
As an observer moves away from the equator, towards the north or south pole, there are more constellations that the rotation of the earth does not ever block from his or her view throughout one full rotation.
Can you see the same constellations from another planet?
No, constellations are patterns of stars as seen from Earth's perspective. From another planet, the arrangement of stars in the sky would appear different due to the planet's position in space. Therefore, you would not see the same constellations as from Earth.
How are meteor showers named?
They're generally named for the constellation they appear to originate from. For example, the Leonids appear to radiate from a location in the constellation Leo, and the Perseids from a location in the constellation Perseus.
Why dont constellations appear in the same spot at the same time all year long?
Constellations appear to shift positions in the night sky due to Earth's orbit around the Sun. As the Earth moves along its orbit, the projection of the stars against the background of space changes, causing constellations to appear in different positions at different times of the year. This phenomenon is known as stellar parallax.
How many constellations are circumpolar?
There's no answer to this question, because the definition of circumpolar depends on where you are. If you're at the pole, all the constellations you can see are circumpolar. If you're on the equator, there are no circumpolar constellations.
