Capricorn or Aquarius?

Capricorn is a cardinal earth sign ruled by Saturn, symbolized by the sea-goat. Aquarius is a fixed air sign ruled by Saturn, symbolized by the water-bearer.

In short: Capricorn is the cardinal earth sign ruled by Saturn. It begins at the December solstice and is associated with ambition, discipline, responsibility and long-term achievement.

Aquarius is the fixed air sign, traditionally ruled by Saturn and, in modern astrology, by Uranus. Despite its water-bearer symbol it is an air sign, associated with ideas, originality, friendship and community.
