Opposition · 180° apart
Opposition
Opposite signs sit across the wheel. Each holds exactly what the other lacks, which makes the pairing either complementary or exhausting.
Earth · Cardinal · ruled by Saturn
Brings. Plans in decades and executes without needing encouragement along the way.
Struggles with. Measures worth by achievement, and struggles to rest without guilt.
In love. Undemonstrative but dependable. Commitment is shown by showing up, not by saying so.
Water · Cardinal · ruled by Moon
Brings. Reads emotional undercurrents accurately and looks after people without being asked.
Struggles with. Withdraws instead of stating the problem, and keeps score in silence.
In love. Slow to open, fiercely loyal once it does. Takes small slights harder than it admits.
Capricorn is cardinal earth; Cancer is cardinal water. Sharing a modality means handling change the same way, which sounds helpful and often means competing for the same role.
Sun signs are one factor among many, and astrology itself treats them as a starting point rather than a verdict. Two full charts describe far more than two birthdays do.
