You are correct on the term planets being "wonderers". If I recall
correctly, that came from the Greek skywatchers.
Yes, many thought the Earth was the center of the solar system. I'm sure
more believed it was the center of the universe as well! In any case, with
the Sun as the center of the solar system, that was some wild "outside of
the box" thinking since the church frowned upon any type of "new findings"
that disputed what the church layed down. Can you imagine being ostracized,
if nothing more serious, in stating and believing that the Sun, not the
Earth, was the center of the solar system? WOW! You'd be excommunicated
and strung up.
Since the planets revolve around the Sun ,and not the Earth, there can't be
any Keps. Keps are based on the Earth being the center of an orbiting
object. I should've recalled that. However, my thinking at the time was if
there are programs which display where to find planets in the sky, like
Starry Night, then there'd have to be a form of calculation to determine it.
I just thought of using the wrong type of calculation.
