“Sun in [zodiac]” what does that mean ASTRONOMICALLY?

670 views

What do you mean when you say “the Sun is in Taurus”. I get that my star sign is Taurus, but what does that mean astronomically? I’m not talking about my personality, I’m wondering how the Sun can be in the same zodiac for a month.

Or does it have nothing to do with astronomy?

I don’t care if astrology is fake or whatever. I’m just trying to understand the expression of “a planet is in this zodical” generally.

Imagine looking down on the solar system, with the sun in the middle and Earth moving in (roughly) a circle around it. It takes a year for that to complete.

Astronomically for the sun to be “in” a constellation you can draw a line from Earth through the sun and out into the stars. Throughout the year this will land you in different constellations, which are the 12 from the zodiac.

These constellations aren’t aligned with the ones astrologers follow since they tend to use constellations based on the day of the year, not actual star positions, which means they’re a few weeks off due to leap years.
