In Hindu Astrology there are nine planets or Grahas. These include Rahu and Ketu, which are astronomical points formed where the moons orbit intersects the apparent path of the Sun around the earth. Each planet is considered to be having masculine, feminine or neutral characteristics

Rahu and Ketu
The Moon's apparent path intersects the ellipse obliquely at two points called the nodes. The point where the Moon crosses the ecliptic from south to north is called the ascending node or Rahu, where it crosses the ecliptic from north to south is called descending node or Ketu. These two points are 180 degrees apart and their movement is constantly retrograde, meaning, against the normal direction of movement of planets. Rahu and Ketu are given special status and considered as planets in Indian astrology. Rahu and Ketu take approximately eighteen years and ten days to complete one round of the zodiac.
The Zodiac is a band 18 degrees wide and placed obliquely to the equator. This band can be imagined running around the earth in an east-west direction. Groups of stars can be located along this imaginary belt. This belt is divided into twelve equal parts called Rasi. It is also divided into 27 parts and each part named after a star or group of stars located in the division When a zodiac is divided into twelve equal parts, each such part has an extension of 30 degrees of arc. Such a division is called a sign or Rasi.
There are 12 houses of Rasi's
