The objects that revolve around sun and do not produce light on their own are called planets.
The very basis of Indian astrology is the nine planets.
Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu.
Apart from the aforesaid nine planets there is a planet called Gulika (Maandi) as well. Gulika is an astrologically significant planet.

9) Rahu and Ketu
These are not real planets but are shadow planets. These are points where the earth’s transit cuts the moon’s transit. They move between the paths of Saturn and Jupiter. When all the planets move forward they move backward. These are imaginary. They take 18 years to complete one revolution around Sun and they remain in one Rasi for 1 ½ years.
