The horoscope functions as a stylized chart/map of the firmament over a particular position at a specific moment in time. In many applications the viewpoint is geocentric. The locations of the actual planets are positioned in the map, along with those of entirely calculated factors like the lunar nodes, the house cusps comprising the midheaven and the ascendant, fixed stars, the lots and zodiac signs. Sharp relationships between the planets themselves and other positions, referred to as aspects, are usually determined. The stress and explanation of these features differs with tradition.
