Ucca (exaltation) is the zodiac sign — and specifically the degree — where a planet is considered strongest and most fully expresses its best qualities. The exaltation points are: Sun at 10° Aries, Moon at 3° Taurus, Mars at 28° Capricorn, Mercury at 15° Virgo, Jupiter at 5° Cancer, Venus at 27° Pisces, Saturn at 20° Libra, Rahu at 3° Taurus (or Gemini by some), Ketu at 3° Scorpio. An exalted planet gives excellent results in the matters of the house it occupies and rules. The closer to the exact exaltation degree, the stronger the effect.
