Description:

The planets in their orbit around the Sun occupy different positions in the sky as seen by an observer on Earth throughout the year.
When the Earth orbits the Sun we see our star projected in the direction of 13 different constellations. These are named the zodiacal constellations.
The time the Sun is projected in the direction of each constellation is not equal in number of days. For instance, it stays 8,4 days projected in the direction of the constellation Scorpius and 44,5 days in the direction of Virgo.
We can build a template that helps to understand how the visible planets to the naked eye move in relation to the stellar background and thus provide its location and visibility in relation to the local horizon.
