The Celestial Sphere + Earth's Annual motion + moon's orbit tilt

North & South celestial poles

• the points in the sky directly above the Earth's North and South poles

celestial equator

• the extension of the Earth's equator onto the celestial sphere

ecliptic

• the annual path of the Sun through the celestial sphere, which is a projection of ecliptic plane

The Earth's axis is tilted 23.5° from being perpendicular to the ecliptic plane.
Therefore, the celestial equator is tilted 23.5° to the ecliptic.

The Earth's Exis precesses (wobbles) like a top, once about every 26,000 years

Moon's Orbit tilted 5 degrees
