The Celestial Sphere Has A North And South Celestial Pole As Well As A Celestial Equator Which Are Projected From Reference Points From The Earth Surface.

Then draw where polaris is and draw the path of a star over. Constellation maps divide the celestial sphere into 88 parts, known as constellations, helping astronomers locate stars and deep sky objects. Rotating the diagram so the zenith is up make it easier to visualize the local sky.

The celestial sphere, the coordinates system, seasons, phases of the moon and eclipses chapters 2 and s1. The extension of the earth's rotation axis to the sky defines the north and south celestial poles (the ncp and scp), while the extension of the earth's equatorial plane defines the celestial equator.
