This is why I’m studying astrology currently to understand what Pali suttas sometimes refer to. One thing I can already say when text place him in heaven of thirty three that is referring to The Big Dipper. So I assume because Buddha was born in Taurus after seven days in the heaven a planet or stars that represents feminine(goddess) was ruling Taurus. See Nalaka Sutta for what was happening in the sky when Buddha was born first to understand everything.

See below that it all makes sense. Because from this website I got this info that connects it to many possibilities. One she is connected with Taurus. And the second she represents wives/sisters of the seven stars that are the Vedic sages. And other things can be also.
But in Buddhism there is a tradition that says that all Buddha mother dies after 7 days. That just means to astrology that the goddess in the sky was descending when Buddha was born or after 7 days it started to descend.
Here is the parts that I feel there a connection to the Buddha.
The Great Goddess and World Mother (Mahadevi) in Vedic Astrology
In Hindu thought, the Goddess is the Mother of the Universe from whom the origin, sustenance and dissolution of everything arises. She governs over the whole of time, as past, present and future, and all of space.
The Goddess is naturally associated with Taurus, ruled by Venus and where the Moon is exalted
KRITTIKA (26 40 Aries—10 00 Taurus), the Pleiades, seven sisters, wives of the seven Rishis (identified with the stars of the Big Dipper)
In conclusion, the Vedic view of the Mother of the Universe and Divine Feminine is to honor all of her forms reflected in time and the sky, from the youthful to the elderly, from the beautiful to the fierce, as mother, sister, daughter, wife and beloved, from the mundane to the Transcendent. This includes a wide variety of astrological and astronomical associations. Understanding the Goddess and the World Mother (Jaganmata, Jagadamba) is essential for understand the Vedic view of time and karma.
By seeing again the above it seems most probably Buddha was born a time where the sun was set at Taurus and Moon at Venus and because Nalaka Sutta says
will set turning the Wheel [of Dhamma]
in the grove named after the seers,
like a strong, roaring lion,
the conqueror of beasts."
That means Buddha was born in Leo rising.
That means the next Buddha might come in same time.
