Most certainly that would be a start. Though I would also want to look at the Moon, Mercury, and Venus signs as well.
Not particularly. This is called Sun sign astrology. For true compatibility oto be analysed astrologically both full natal charts must be compared.
the part when mrs.hilcher and sun sun start doing things together
maybe yes, because sometimes star sign do affect. so sun sign may also affect...?? don't get affected by those signs, they are not always correct. actually personality and character mean more
You can't be a Capricorn Leo as you can only have your Sun sign in one astrology sign, but it is possible to have your Sun sign in Capricorn and your ascendant in Leo. Also it's impossible to have an ideal compatibility with anyone, but two people can be a very good match for each other. To see if you are compatible with another person you will need a relationship chart and report that interprets the Sun, Moon and planetary signs, angles, aspects and houses. Any professional astrologer myself included can do this for you.
It simply means that your friendship will not end.
Compatibility in astrology does not rely on just Sun signs; Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto signs, angles, aspects and houses are also used. So if one person has their Sun sign in Taurus and the other person has their Sun sign in Gemini they can be compatible in marriage.
Astrologically compatibility with another person relies on more than just the Sun signs; the other planetary signs, aspects and houses need to be used too.
As per vedic astrology, Capricorn sun sign or moon sign is compatible with Leo even they are in 6th and 8th direction. This due to special sign aspect between them
His sun sign is Leo and his moon sign is Aries.
Mostly other Earth signs, like Virgo and Tauras. It is more important to check your moon sign, because this is probably even more important then the compatibility of your sun sign. Moon signs can actually show how two people can live with each other.
There is no such thing as a Sun's plus sign in astrology.
It depends on the date and place of birth. They could have their Sun sign in Gemini or Cancer. To find out their Sun sign an astrology chart would have to be created using the date, place and time of birth.
