And the rising sign or ascendant, which is the sign that was rising (or ascending) on the eastern horizon at the time of your birth, shifts throughout the day, spending about two hours in a sign. While the sun might have been in Leo, the moon, which moves pretty fast - it switches signs every two to two-and-a-half days - could have very well been in mutable water sign Pisces or cardinal air sign Libra. (For example, check out how Harry Styles's birth chart totally makes sense for him, as does Doja Cat's.)
All these different points combine to create an astrological profile that's uniquely you.
The position of the planets and luminaries will be depicted in a circle chart, which represents the sky (though some apps or websites present it in a list format). Basically, your astrological birth chart is a snapshot of the sky - documenting where the planets, luminaries (the sun and moon), and other key celestial points and bodies were from your vantage point on Earth at the precise moment when you were born.
