If observed through the year, the constellations shift gradually to the west. This is caused by Earth’s orbit around our Sun. In the summer, viewers are looking in a different direction in space at night than they are during the winter.
Then, when do constellations appear?
The chosen answer was each constellation is best seen in the evening sky at a certain time of year, whether it only briefly shows up above the horizon or it is visible throughout the year from a certain location. Below is the list of constellations visible at 9 pm each month. These are not all the constellations that can be seen in the evening sky at any particular time, but simply those that are best observed at the given time of year.
This of course begs the question “How do the constellations change from season to season?”
I discovered the constellations that are visible in the night sky in the evening change from season to season because stars appear to move by 90 degrees across the sky every three months.
Summer and winter constellations are different because stars in fact take a little less than an hour to move by 15 degrees, and they complete an entire circle in 23 hours and 56 minutes. In other words, they rise and set four minutes earlier each night.
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.
Some authors claimed The months listed assume that you are looking at the sky at 9:00 PM. For every hour later than 9:00, add half of a month. For every hour before 9:00, subtract half a month. The constellations are typically visible for more than just one month, depending on where you are on the Earth.

If you need to know exactly when a constellation is visible, check in a star atlas or on a planisphere.
Are constellations real?
Constellations have imaginary boundaries formed by “connecting the dots” and all the stars within those boundaries are labeled with the name of that constellation. However, keep in mind that constellations are not real objects; they are just patterns as seen from our observation point on Earth.
The next thing we wanted the answer to was, are constellations real or just patterns?
However, keep in mind that constellations are not real objects; they are just patterns as seen from our observation point on Earth. The patterns we see are for the most part just by chance. The individual stars in a constellation may appear to be very close to each other, but in fact they can be separated by huge distances in space.
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.
The constellations you can see at night depend on the time of year. Earth orbits around the Sun once each year. Our view into space through the night sky changes as we orbit. So, the night sky looks slightly different each night because Earth is in a different spot in its orbit.
The constellations are totally imaginary things that poets, farmers and astronomers have made up over the past 6,000 years (and probably even more!). The real purpose for the constellations is to help us tell which stars are which, nothing more. On a really dark night, you can see about 1000 to 1500 stars.
How close are stars in a constellation to each other?
The individual stars in a constellation may appear to be very close to each other, but in fact they can be separated by huge distances in space and have no real connection to each other at all. For example, look at the image below of the stars which make up the constellation Orion.
