Example text

The diagram shows the degrees measured by each of these hand positions. From day to day and from hour to hour, the constellations in the sky appear to move. On a star map, this movement is in a counterclockwise direction around Polaris. A single constellation moves about 361° every 24 hours. There are 360° in a circle. This extra degree of constellation movement adds up to about < previous page page_35 next page > < previous page page_36 next page > Page 36 30° a month. M. M. M. on April 1 it was 30° to the left (to the east if facing south) of the position shown on the May star map.

This movement causes the stars to appear to move overhead. The exit points of Earth's axis are called the South and North Poles. The South Pole is in the Southern Hemisphere (the region south of the equator) and the North Pole is in the Northern Hemisphere (the region north of the equator). The end of the axis at the South Pole points in the general direction of a constellation called Corona Australis (kuh-ROH-nuh awSTRAY-lus). Because its star pattern resembles a cross, this constellation is often called the Southern Cross.

When the observer is at latitude 90°N on Earth, the zenith is declination +90° on the celestial sphere. The group of visible constellations from this latitude is different from those for observers at other latitudes. Different positions of the pointer represent different latitudes for observers on Earth. At different latitudes, the zenith and horizon change. For example, when the observer's zenith is at +90°, the constellations seen are A through F. At -45°, constellations F, H, I, and part of G are visible.
