Dear friend,
I have represented the venus analemma for 2 next years as follow
pos = $GeoLocation
zone = $TimeZone
analemmavenus = Table[{
    AstronomicalData["Venus", {"Azimuth", {2011, 1, i, 6}, pos},
     TimeZone -> zone],
    AstronomicalData["Venus", {"Altitude", {2011, 1, i, 6}, pos},
     TimeZone -> zone]}, {i, 1, 2*365.25, 10}];
Graphics[{Orange, Point[analemmavenus]}, Frame -> True,
 FrameLabel -> {"azimut", "altitud"}]

Is it taken into account when the planet is behind the Sun?
It the answer is negative. How can be taken into account that a planet
is  behind the Sun?
