Venus         - "The Goddess of Love and Beauty" (Aphrodite)

As we know from Mythology, she's all about Beauty and the Heart. She's about our desires, our value system, Art and Beauty as well as romance, love and sexuality. What is important to us, how do we define what is beautiful... These are not decisions we make from our logic mind but from our heart-mind. As she's also about desire, it can bring her themes into imbalance and bring forth jealousy, greed and competition thinking...
Because she's the value system, she also governs money and financial affairs as well as all kind of property. She is "magnetic" in energy and is about our vascular system and the heart chakra. 
Did you know? A Scientist with name J. A. Armour did find out, that the Human heart contains neurons - so, there is a "brain" in the heart - wonderful also this is now an old knowing that is scientifically proven....
As we're having this "heart-brain" and it's direct connection to the "gut" as well as the mind, we can understand that Venus' theme goes much deeper than the physical world - the values we set are also talking about ourselves and how we actually think of ourselves, how we define ourselves and what we belief of ourselves as possible.... 
Imbalance can lead to jealousy, greed and other similar expressions.

Greek Mythology: Aphrodite was born from the sea and titled the Goddess of Love. She seeded passion and desire into the hearts and was so about marriage and adultery. She was also a jealous type - she couldn't stand anyone else to be more beautiful.

Some Astronomy: Venus lies within Earth's orbit, and so never appears to venture far from the Sun, either setting in the west just after dusk or rising in the east a bit before dawn. Venus orbits the Sun every 224.7 Earth days. Venus spins around her own axis very slowly and as Uranus from east to west, and takes her 243 Earth days to rotate once around her axis - this means, that one Venusian year is slightly shorter than one Venusian day... sounds odd, I know.... Her orbit is very round - the most circular (difference only 0.006) of all Bodies we know so far in the solar system.
Venus is a terrestrial planet  and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. (Ref. Wikipedia/ Nasa)

Venus Cycles:

Every almost 8 years, Venus forms a Synod with Earth every 584 days (ca 1,6 years) about 7 signs apart, therefore it takes 5 cycles for the synod to be "back" and forming-completing a 7,97 years cycle. A next Pentagram will be formed about 2degrees shifted from the previous one... to be completed, it takes 243 years from Southnode to Southnode. In between - though every 121.5 years, it's a cycle of the Northnode....

Each of the smaller cycle is embedded in it's larger cycle and all of them are defined by the zodiacal position and star alignments....

The Phases of Venus as seen from Earth

Phases-of-Venus-disk.jpg

Here’s the planet Venus seen through a telescope beginning in late February 2004. As the months passed, the planet waned in phase, because we saw less of its day side. Meanwhile, Venus appeared bigger and bigger from Earth, because it was traveling closer to us in its smaller, faster orbit. Finally, in August 2004, Venus passed between the Earth and sun. At that point, it exhibited a “new” phase with its dayside turned entirely away from us, and a rim of light seen shining around the planet through its thick atmosphere.
