Chapter 2 discovering the universe for yourself. The celestial sphere y the stars in a particular constellation appear to lie close to one another but may be quite far apart in reality, because they may lie at different distances from earth.

It crosses the celestial equator at a 23. 5r angle, because that is the tilt of earth s axis.
