Why are there constellations visible in Northern Hemisphere but not in Southern Hemisphere & can certain constellations only be seen in Southern Hemisphere?
That's because this constellation is directly north of Earth's axis. As Earth orbits the Sun, the dipper appears to move in a circle around the sky. For this reason, it is called a circumpolar constellation. People in the Southern Hemisphere can't see the Little Dipper. While the North Pole faces outwards to the Universe beyond, the South Pole points to the galactic centre of the Milky Way. This means more bright stars and more constellations containing more stunning objects. Plus, everything in the southern hemisphere sky will look upside down, if you're used to northern skies. Moreover, all constellations in the Southern Hemisphere are not visible in the Northern Hemisphere and vice versa. This is because the earth is round and some constellations do not fall in the line of sight. A person on the equator can see almost all the constellations.
Southern circumpolar constellations include Phoenix, Grus, Tucana, Eridanus, Hydrus, Lupus, Cruz, Centaurus and Carina, among others. The changing sky has always fascinated mankind. So, humanity created myths and legends about the moon and stars. Just as in the Northern Hemisphere, the southern night sky is divided into constellations. There are 88 constellations in all; 32 of them are found in the Southern Hemisphere. This happens because the horizon does not allow us to observe all the stars contained in the sky. There is also the fact that some constellations belong to the Northern Hemisphere and others to the Southern Hemisphere. This is because of the Earth's tilt axis. Orion is in the southwestern sky if you are in the Northern Hemisphere or the northwestern sky if you are in the Southern Hemisphere. It is best seen between latitudes 85 and minus 75 degrees. Since the sun only shines for about half the day, you lose sight of constellations blocked by sunlight. Plus, because the Earth is orbiting the sun, you can see different parts of the sky depending on the time of year. Even so, there are some things you can't see at all depending on which hemisphere you live in. Because of its position, people in the Northern Hemisphere can see the Little Dipper throughout the year. The dipper appears to move in a circle around the sky as Earth orbits the Sun, so it is a circumpolar constellation. People in the Southern Hemisphere cannot see the Little Dipper. The northern circumpolar constellations you'll find are Ursa Major, Ursa Minor, Perseus, Lynx, Draco, Cepheus, Cassiopeia, Camelopardalis and Auriga.

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. If observed through the year, the constellations shift gradually to the west.

Finding Orion's Belt is the easiest way to locate the Orion Constellation. Orion's Belt is formed by three bright stars; Alnilam, Mintaka and Alnitak. Orion is in the southwestern sky if you are in the Northern Hemisphere or the northwestern sky if you are in the Southern Hemisphere. This is due to the fact that since the Earth rotates on an axis that points north, which would be on the horizon from a person at the equator, all stars and constellations rise and set. Draco is circumpolar, meaning that it never sets below the horizon and is always visible in the Northern Hemisphere, but cannot be seen in the Southern Hemisphere. The Southern Cross is an asterism made up of the most visible stars in the constellation Crux. The iconic group of stars is visible mainly from the Southern Hemisphere.
