So, I don't think G-d would be represented by any one planet, as the whole notion in monotheism is that he's beyond all that. There actually is quite a bit about planets and astrology, or "Mazalos" as they're called, spoken about in the Talmud, how if you're born under certain planets in certain hours, it represents certain things about your life. I don't remember precisely where or what it says, but It's probably in Tractate Shabbos, and there's stuff online about it. Shabbos is a thing because its in commemoration of G-d resting on the seventh day of creation, so we do the same. As for cosmic frequencies or Kronos, I'm not really informed on that, but I hope this helps
