Question

What is my personality like?

Your Sun is at 28° Taurus, in the 9th House. In traditional astrology, a Taurus Sun is often used to describe a slow, steady, unhurried pace; the 9th House is linked to faraway places and the search for meaning. Your Sun also squares Mars, a pattern often read as a will that doesn't give way easily beneath a calm surface.

Cosine Astro isn't fortune-telling. It treats astrology as a cultural language for self-reflection: it doesn't predict your fate, doesn't hand down verdicts, and doesn't replace professional advice.
