KosmosAre you compatible? This category explains what zodiac sign compatibility actually tells you, how the system of elements works, and why a proper Relationship Horoscope Book (synastry) compares both full birth charts across all the planets rather than just two Sun signs. You will also find articles on Venus, Mars, and the Moon in love.
You can explore all 78 sign combinations in the compatibility table, each with its own page. For an honest look at your connection, there is the Relationship Horoscope Book and the Composite Chart Book, or, for something shorter and quicker, Astro Bites for two.

Frequently asked questions about Relationships
Which star signs are compatible?
Signs in the same element usually understand each other easily. Fire and air complement each other, as do earth and water. This is a tendency, not a verdict: the Moon, Venus, Mars, and the aspects between both birth charts all matter in a relationship.
What is a Relationship Horoscope Book?
A comparison of two complete birth charts (synastry). It shows where your planets support each other, where they create friction, and what you can learn from one another, far more precisely than any Sun sign table.
Do we need both birth times for a Relationship Horoscope Book?
Birth times help, because they bring both people's Ascendant and houses into the picture. Without them, the planets by sign and their aspects to each other can still be determined, which accounts for the greater part of the interpretation.
