Constellations
Constellations have fascinated astronomers for centuries. They are arbitrary formations of stars perceived as a figure or design, especially one of 88 recognized groups named after characters from classical mythology and various common animals and objects. Questions about the various constellations of stars are what this category is all about.

Why did they name it the little dipper?
I suspect that once the more obvious asterism of the Big Dipper was named, the nearby and similar group was simply called the Little Dipper.
World cultures did not always agree, (heck, they almost never agreed) on which stars were in which asterisms, or what they represented. The which we call the Big Dipper has variously been The Plow, The Sickle, The Cart, the Great Bear (hence the constellation of Ursa Major, which is the Big Dipper plus some other stars) and, in the years following Charlemagne, Charles' Wain (wagon).
Note the distinction between asterisms, which are groups of stars seeming (often to those with strong imaginations) to form animal or other shapes, and constellations, which are tracts of sky, very like countries on a geopolitical map.
Some asterisms are the hearts of constellations, as the Big Dipper is part of Ursa Major, but some are larger. The "Summer Triangle" of Vega, Deneb and Altair takes in parts of three constellations.
Why do astronomers use modern constellation regions?
Constellation are a useful quick way of dividing the sky up into its different regions, so astronomers have continued to use the traditional constellations.
Unfortunately, constellation boundaries are made more complicated to define because of precession, which means that some boundaries that used to follow lines of constant right-ascension or declination no longer do so. This means that star atlases have to be redrawn every 50-100 years.
Why can you see different constellations every month?
That is because we go round the Sun. That means that every day the stars we see at midnight shift to the right by about 4 minutes of time. The stars that were due south last night at midnight will be due south at 23.56 tonight and by midnight they will be a little further west. Through the course of a year the stars that happen to be due south at midnight rotate right round the full circle.
What was the first constellation named?
The human construct of using star formations and equating them with living and inanimate objects goes back to the origins of our species. It is impossible to determine who drew the first ideas and names of the stars and their positions. What is known is that major constellations such as the Big and Little Dippers have names across different world civilizations indicating ancient cultural commonalities in astronomical observations.

Are constellations different in each season?
because during the summer the northern hemisphere is tilted toward the sun and the southern hemisphere is tilted away. this tilt of our planet is about 21 degrees and shows us different views of the night sky as we tilt back a forth with the seasons. So in the winter you would see a lower portion of the sky and in the summer you are seeing a higher portion of the sky.
You will be able to see many of the same constellations (called circumpolar constellations since they are near the poles and can seen year round) but constellations closer to the horizon and closer to the equator will change
