The Rulership of the Nakshatras
The exact nature of each Nakshatra is better understood by observing the combinations of Elemental Energies and Modalities they represent. For example, even though all 3 Nakshatras of the Moon are in the mid section of Earth Signs, so the strong Earth energies are shared, but Rohini is Fixed, Hasta is Mutable and Shravana is in a Cardinal Sign, so 3 people with these 3 (ruled by the Moon) Nakshatra placements of the Moon will be very markedly different in nature, even though each will have strong practicality and structure.
Ketu rules the Nakshatras of Ashwini, Magha and Mula. Ketu’s Nakshatras are always in the exact beginning of each Fire Signs (Aries, Leo, Sagittarius)
Venus rules the Nakshatras of Bharani, Purva Phalguni and Purva Ashada. Venus’s Nakshatras are always in the second half of the Fire Signs, almost, but not quite, reaching the border with the subsequent Earth Signs.
Sun rules the Nakshatras of Krittika, Uttara Phalguni and Uttara Ashada. The Sun’s Nakshatras are always bridging the Fire Signs (Aries, Leo, Sagittarius) and the following Earth Signs (Taurus, Virgo, Capricorn.) The bigger portion is always in the Earth part.
Moon rules the nakshatras of Rohini, Hasta and Shravana. The Moon’s Nakshatras are always within the middle part of the Earth Signs (Taurus, Virgo, Capricorn)
Mars rules the Nakshatras of Mrigasira, Chitra and Dhanishta. Mars’s Nakshatras are always bridging the Earth Signs (Taurus, Virgo, Capricorn) and the following Air Signs (Gemini, Libra, Aquarius)

Jupiter rules the Nakshatras of Punarvasu, Anuradha and Purva Bhadrapada. Jupiter’s Nakshatras always bridge the Air Sigs (Gemini, Libra, Aquarius) with the following Water Signs (Cancer, Scorpio, Pisces) The bigger portion is within the Air part.
Saturn rules the Nakshatras of Pushya, Anuradha and Uttara Bhadrapada. Saturn’s Nakshatras are always fully within the Water Signs (Cancer, Scorpio, Pisces)
Mercury rules the Nakshatras of Aslesha, Jyeshta and Revati.
