The term ‘Planet' is derived from the Greek word for wanderer and in astrology encompasses a number of celestial bodies that strictly speaking, aren't technically planets at all. These include the Sun (technically a star) the moon ( a satelite) and Pluto (reclassified as a planetoid). You will also find hypothetical points such as the North and South Nodes and Chiron, which is a centaur. Certain astrology reports will also incorporate the use of fixed stars, although this is less common and not recommended for beginners.

In astrology, each planet has its own set of archetypes or characteristics that find expression through the zodiac sign that they are located in and in an area of life defined by the house they are placed in.

In medieval times the seven known planets ruled a day of the week, so it is often interesting to look at the placement of your birth planet in relation to both your natal horoscope and current transits.
