Meridian (astronomy) This implies that an observer has no local meridian or antimeridian when the zenith is on a celestial pole. In the horizontal coordinate system the meridian is divided into halves terminated by the horizon's north and south points. The upper meridian passes through the zenith, and the lower meridian, through the nadir. A celestial object will appear to drift past the local meridian as the Earth spins, for the meridian is fixed to the local horizon. The object reaches its highest point in the sky when crossing the meridian (culmination).
