Rahu does not rule any zodiac
Rahu (North Lunar Node) is node positioned at the meeting point of
the earth's trajectory around the Sun and the Moon's trajectory
around the Earth meet. It represents the head of demon and is
responsible for Solar eclipse. This happens when Rahu, Sun and the
Moon are in the same zodiacal longitude.
According to Indian mythology, Rahu Graha is a 'shudra graha.'
People influenced by it behave like illiterate and uncultured. Rahu
rules over thieves, witches, magicians, venom and poison, snakes and
thorny bushes, jails and isolated places, unhabitated places,
cemeteries, hypnotists etc.
In Puranas it is said that Rahu is instrumented in strengthening
one's power and converting even an enemy into a friend. It is also
often called the Planet of Success. Since Rahu is not a real planet
it does not rule any zodiac.
