Why are the nine English planets not considered in Indian astrology?

Here are some ideas, any or all of which might explain why Indian astrology doesn't include "the nine English planets" as was asked. We'll just toss a few facts out and, though they may "jump around" a bit, it is hoped they paint a picture that, when conceptualized, reveals an acceptable answer to this question.

Astrology has been with man since before recorded history. People have looked to the stars in their superstitious ways probably since not long after man began walking upright. Superstition is a part of all cultures across all the peoples of the world from all times recorded. It is almost as if man has evolved with a "superstitious" gene. How could one not embrace the idea that some form of "astrology" or, at the least, a "belief in spirits" has existed from near the time of the dawn of man?

The earliest known writings on astronomy belong to the Babylonians. Their records date back 5000 years, and their idea of celestial omens is systematized in their ancient records. The concepts spread through the Middle East, notably to the Assyrians. They also made their way to Greece, Egypt, India and to China.

[Interestingly, the first actual stone construction at Stonehenge is thought to have begun about this time. The stones were late additions to much earlier timber structures, which were, themselves, predated by earthen berms or mounds.]

The people of India are the proud inheritants of a long history that dates back at least 9000 years to the first known permanent settlements. Some 5000 years ago, a sophisticated culture began using symbols to communicate - writing. Written Vedic works dated to a few centuries before Christ speak to the Jyotiṣa. And it (the Jyotiṣa) is early Indian astrological belief, though it could be fairly argued, from the Indian point of view, that it is more "religious" than it is "occult" which is the way it may look to us.

The British didn't begin to have a wide influence in India until the 1600's, when the early trading companies were being set up. Indian astrology certainly predates this historic evolution, that is, the establishing of trade as a prelude to the conquest of India and the extension of the British Empire to this land and its people. The broad inclusion of English ideas probably does not predate this historic era by much, if it does at all.

Of the "nine English planets" that we know so well, the last three are not visible to the naked eye Their inclusion in any horoscope represents a de facto "late addition" to an existing system of divination. Those last planets, Uranus (dis. 1781), Neptune (dis. 1846) and Pluto (dis. 1930) could have been incorporated only recently.

[It will be interesting to see how astrology adjusts to Pluto's "downgrade" to a dwarf planet (134340 Pluto) and to the discovery of dwarf planet Eris (136199 Eris) in the year 2006. And why is Ceres (1 Ceres) discriminated against?]
