Most horoscopic traditions of astrology systems divide the Horoscope into a number (usually twelve of houses whose positions depend on time and location rather In Astrology, a horoscope is a chart or diagram representing the positions of the Sun Moon planets the Astrological aspects, and sensitive angles This house system divides the prime vertical into equal 30° arcs, or houses. In Astronomy and Astrology, the prime vertical is the Vertical circle passing east and west through the Zenith, and intersecting the Horizon

In the field of astronomy, he wrote a Theorica Planetarum in which he geometrically described the motions of the planets as well as their longitude. A planet, as defined by the International Astronomical Union (IAU is a celestial body Orbiting a Star or stellar remnant that is Longitude (ˈlɒndʒɪˌtjuːd or ˈlɒŋgɪˌtjuːd symbolized by the Greek character Lambda (λ is the east-west Geographic coordinate measurement He also included instructions on building a planetarium as well as its geometrical description. A planetarium is a Theatre built primarily for presenting educational and entertaining shows about Astronomy and the night sky or for training in Celestial navigation This was the first description of a planetarium by a European. The European peoples are the various Nations and Ethnic groups of Europe. Campanus also attempted to determine the time of each planet's retrograde motion. Direct motion is the motion of a Planetary body in a direction similar to that of other bodies within its system and is sometimes called prograde motion. The data on planets are drawn from the Almagest and the Toledan Tables of the Arab astronomer Arzachel. Almagest is the Latin form of the Arabic name ( الكتاب المجسطي, al-kitabu-l-mijisti, i Gerard of Cremona (1114–1187 edited for Latin readers the Tables of Toledo ( Toledan Tables) the most accurate compilation of Campanus gave precise instructions on using the tables, and made detailed calculations of the distances to the planets and their sizes.
Campanus also wrote Tractatus de Sphaera, De computo ecclesiastico and Calendarium.
