The apparent path of Venus as seen from the Earth with respect to the
Sun is roughly a 5 sided figure, but it isn't a perfect pentagram by
any means. It's loopy and squashed.

Does someone have a link to an image of this so called pentagram? I
just ran Venus through the evening sky for 2005 in a planetarium
program and the planet made a sort of a figure-8 pattern. What does
this pentagram look like?

Bill Owen answered this as well as I can, but I can add, that I also
read 'that book' and thought it was an evening well spent, except I
didn't see one word that made me think anything was true....

When I found the section on Venus' pentagram, I pulled out one of my
favorite books:

Schultz, Joachim. Movement and rhythms of the stars.
Edinburgh: Floris, 1986 (transl. from German 1963).

Which is full of beautiful drawings of celestial movements - planets,
eclipses, sun, moon, stars.

On p121 is an image of "The geocentric Venus orbit 1960-68", with earth
at the middle, and the constellations at the rim, with Venus tracing a
loopy round 5 pointed star - looks more like a five pointed flower.
Then the next pages show 'Distribution and sequence of the superior
conjunctions of Venus and Sun 1952-61', and then inferior conjunction -
traced in a five pointed star.

I'm sure a planetarium program can replicate these if the right input is
provided....
good luck
