Question

DOB 6/25/65 :: 06:27EST(US-Florida)

I can see the Placidus Orbs in Houses I-XII , and the positions of each planet, LiLith and Asc node (Don't know what these two mean at all).

I am

Sun:Cancer

Asc:Cancer

Mer:Cancer

Ven:Cancer

But, I do not know how to determine anything else meaningful from this data.

Answer 1

Ascendant is another name for 1st house of "self".

Descendant is another name for 7th house of partnerships.

Answer 2

your descendant is the opposite of the ascendant and will probably be in capricorn being that your ascendant is in cancer.

Answer 3

Your descendant is directly opposite

of your ascendant

and is on the right side of your chart

It should be Capricorn if your ascendant is Cancer
