Polaris - is a star in the northern circumpolar constellation of Ursa Minor. It is designated α Ursae Minoris and is commonly called the North Star or Pole Star.

A constellation - is a group of stars that appears to form a pattern or picture like Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Constellations are easily recognizable patterns that help people orient themselves using the night sky.

Earth's rotation - As the spin of the Earth carries us eastward at almost one thousand miles per hour, we see stars rising in the East, passing overhead, and setting in the West. The Sun, Moon, and planets appear to move across the sky much like the stars.

East to West - Diurnal motion is the daily motion of stars and other celestial bodies across the sky. This motion is due to the Earth's rotation from west to east, which causes celestial bodies to have an apparent motion.

ORION constellation of Ursa Major - It is one of the easiest constellations to find at night in the Philippines. Orion was legendary. The Greeks believed that their god Zeus placed ORION among the stars when he died.

Anticlockwise direction - The movement of the Earth around the Sun in a fixed path is called a revolution. The Earth revolves from west to east.

The Little Dipper (Ursa Minor) - is a circumpolar constellation. The constellations are still there during the day. You just can't see them because the Sun is so bright.

Orion - is most visible in the evening sky from January to April, winter in the Northern Hemisphere, and summer in the Southern Hemisphere.

88 Constellations - Originally the constellations were defined informally by the shapes made by their star patterns, but, as the pace of celestial discoveries quickened in the early 20th century, astronomers decided it would be helpful to have an official set of constellation boundaries.

the night sky changes because of Earth's orbit around the Sun - is that the night sky changes because Earth's orbit around the Sun, and as you'll see, this also explains the path called the ecliptic on the celestial sphere.

Hope this helps good luck and stay safe always <3
