The answer is always the same .. Although the constellations are not usually stars which are physically associated with each other, you have to go a very significant distance from Earth before you would be able to see them appear as different shapes. Everywhere within the solar system the constellations would look just the same.

Why do stars and constellations stay in the same spot?
Stars and constellations stay in approximately the same spot for many, many years. They only appear to move in the sky during the year because we are on a moving planet. Because the constellations are in a fixed location, they are often used as landmarks in the sky.
Why do constellations look the same after several years?
(Intermediate) It is said that all stars are moving at different speeds and directions.
Astronomers today still use constellations to name stars and meteor showers. A constellation is a group of stars that looks like a particular shape in the sky and has been given a name. These stars are far away from Earth. They are not connected to each other at all.
But it’s not the shape of the constellations that changes, no, the distances between the stars in one pattern and their mutual positions always* remain the same, but their orientation and location in the sky! *To be precise, the stars in one constellations are neither gravitationally bound nor are they close together in space.
Are all the Stars in a constellation the same?
, and not necessarily. Each constellation is a collection of stars that are distributed in space in three dimensions – the stars are all different distances from Earth. The stars in a constellation appear to be in the same plane because we are viewing them from very, very, far away.
A frequent inquiry we ran across in our research was “What are constellations in astronomy?”.
Constellations are groups of stars. The constellations you can see at night depend on your location on Earth and the time of year. Constellations were named after objects, animals, and people long ago. Astronomers today still use constellations to name stars and meteor showers.
Some stars in a constellation might be close while others are very far away. But, if you were to draw lines in the sky between the stars like a dot-to-dot puzzle – and use lots of imagination – the picture would look like an object, animal, or person.
Today, there are 88 officially recognized constellations. This group of stars is called the “big dipper.” If you trace a line between the stars, it looks like a ladle, or dipper, that you’d use to dip soup from a pot.
What is the meaning of a constellation?
A constellation is a group of stars that looks like a particular shape in the sky and has been given a name. These stars are far away from Earth. They are not connected to each other at all.
