Constellations are far away from each other.

The word constellation came from a Latin word “cōnstellātiō” which means set of stars.

Stars give off energy as heat and light.

As the earth rotates on its axis, the constellations appear to be rotating clockwise in the sky.

Spica is the hottest because it gives off a bluish light while Betelgeuse is the coolest because it gives off a reddish light.

Sun is the hottest star.

Ursa Major is the largest northern constellation and the third largest in the night sky. The brightest stars of this constellation form an asterism known as the Big Dipper.

The visible stars in each constellation are closer to planet earth.

Constellations may be only visible during certain seasons due to the Earth's revolution around the sun.
