Hi as you are Capricorn asc, your Seventh house is cancer, so your Ketu sitting in 7th house as well as in cancer sign so you may be less emotional or less sentimental and more practical… second thing 7th house Ketu placement causes dissatisfaction from your partner, spouse and your business partner may cheat on you.

Jupiters placement here in cancer sign shows exalted jupiter and it has aspects where ever ketu is aspecting so your luck with shine more after marriage and you will get your partner from well cultured, orthodox family too. Even though you will get better spouse but you will have some sort of dissatisfaction on long run.

Sun in 7th house got eclipsed by Ketu here so you may have egoless personality and may lack confidence in the first half of your life. 2ndly placement of SUN with Venus and jupiter would combust both of them so positive effects of venus and jupiter would be lost and there would be some ego problem with your spouse and other people. Venus would do the best here as you would always taking care of your spouse.. so overall there will be tug of war between SUN+ KETU Vs. Venus+Jupiter… but overall venus would protect your marriage life but there would be excitement always..
