Sun
The Sun is a star. Astrological language includes it among chart factors and calls it a luminary.
How it is defined
Placing a factor in a chart requires a date, an instant and a reference frame. Sign, house and aspect answer different questions: zodiac position, chart sector and angular relationship. They should not be treated as interchangeable.
How to read it
Its symbolic image explores purpose, conscious expression and the direction you want to develop.
A concrete example
In a project, distinguish the goal that interests you from the approval you hope to receive. This explores solar symbolism without reducing your entire identity to it.
