A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black dot moving across the face of the Sun.
The opposite of where a larger object passes in front of a smaller one is called covering. The Venus transit is the place where the planet Venus sweeps across the face of the sun when viewed from Earth.
Now this event is really very rare. In fact, it has only happened about 25 times since the Romans arrived in Britain. And only about 7 times since the telescope was invented.
There was one in 2004 and there is one in 2012 and if you miss that 2012 the next one December 10th and 11th 2117. So why 2 in 8 years and then none for 105 years? Because of the movement of Venus and Earth, it takes over a year and a half for Venus to overtake Earth again. Compared to Earth about 3.5 degrees, this means that a transit does not take place every time Venus overtakes Earth.
In fact, a transit can only take place where Venus crosses the plane of the earth's orbit. This is done in two positions. One is called the ascending node and the other is called the descending node.
It takes Venus about 225 days to orbit the sun and earth, apparently 365 times. This means that 8 orbits of the earth and 13 orbits of Venus take roughly the same time. So if there is a year of transit, then there could be one 8 years later.
It's not exactly 8 years, so the exact alignment will be very slightly different in each 8-year period. In 2004 the transit moved over the lower half of the sun. In 2012 it will be above the top half.
And in 2020 it will completely miss the sun. Because of the small difference every 8 years they will be realigned the next time they are more than a century long. So why are Venus transits historically significant? Before we observed a Venus transit, we knew the relative size of the solar system, for example, we knew Venus roughly 72% of the way between the sun and earth is, but we didn't know how many miles it was.
So we are actually able to use the parallax effect when we have observers at both ends of the earth, and we can use the tiny change in the apparent position of Venus to find out how far it is and how far we are from Venus away are sun. The difference is actually quite small. It's about a minute of arc.
That is 1/60 of a degree. You can see the parallax effect for yourself by holding a finger forward and alternately closing your right and left eyes. The apparent position of your finger appears to be changing against the background.
The idea is simple. If you can observe the exact times that Venus enters and exits the Sun's disk in different positions on Earth, you can calculate how much of a shift in position you have taken and how far away Venus is . In the 18th and 19th centuries, some people traveled for many, many months, sometimes with great personal effort, to observe the transits of Venus.
Some were unsuccessful due to serious illness or clouds of the exact time that Venus walked or entered the solar disk was thwarted by a strange phenomenon known as the black drop effect. Here, instead of the exact moment Venus touched the edge of the sun, there appeared to be a sharp edge that Venus was just merging with the edge of the sun. That made the timing very, very difficult indeed.
Unfortunately, although some of the earliest estimates of the size of the solar system in the sun without adequate protection and sunglasses are not enough, some of the early measurements turned out to be quite inaccurate. One of the best things you can do if you have a telescope to project it onto is a sheet of paper and watch the sheet of paper, or you could set up a simple pinhole camera so thanks for watching.
Within your birth chart, Venus governs courtship and adoration, as well as personal taste and aesthetics. Venus represents your values, including your relationship with finances and material possessions. This planet is all about pleasure, so Venus just sits back and relaxes while it gets exactly what it wants. .
They are all the same woman. Who do you recognize? Why? How did the Venus de Milo, an armless ancient statue, go from missing on a tiny Greek island to an international icon? She is part of a story that spans centuries - and a possible one Cover-up that starts here with a missing piece. This sculpture is so popular that you can easily find a 3D scan of it, it's really good quality - and then get it printed.
And the sculpture itself gives a clue of its popularity because it contains its story. I really hope I don't screw this up. The story is hidden right here in the seam.
In 1820, a Greek farmer discovered marble carved on his land A woman's pieces. He sold what he did to the French for about 1,000 francs - about $ 11,000 today - enough for a decent used car. They took this home with them - a Venus split in two, along with some other scattered marble fragments.
Venus has a number of shortcomings: the arms were no longer attached. Other defects marred the body. She was missing uh earlobes - probably taken from looters.
One foot was gone, right here. And a likely base - called a pedestal - had broken off. That would have been right here.
Each half should be connected in the middle with iron tenons - imagine two metal bars connecting the two halves. The rest of the pieces likely fell off due to age. When it was assembled, its scale was really impressive, at 6'7 inches high and with features like a 12 and a half inch feet tall.
Shaq-like foot. But Venus's appearance wasn't the most important factor in its success. You have to have to look at the circumstances under which it was excavated and the French art world - it was in turmoil.
This drawing of the Sphinx was made by Napoleon Bonaparte's personal art thief VivantDenon. He drew them during his tour of Napoleon's Egypt looking for art to loot. Classical art was considered the most sought after - a connection to the greatness of Rome and Greece.
While Napoleon spent 20 years conquering the world, Denon t took over from anywhere Napoleon was successful. He ran the Louvre museum under Napoleon's rule and filled it with the art he had stolen. When Napoleon lost his throne, this vast treasure trove of classical art had to be returned to its owners, and suddenly the Louvre - and France - had a huge problem.
For example, the Vatican got Laocoon and his sons and the Apollo Belvedere back, and the Italians were reunited with their own plundered Venus, Venus de Midici. The Louvre wasn't empty, but it was desperate. Five years later, Venus appeared on a Greek island.
The French were ready to do whatever it takes to replace the classical art they had lost when Napoleon was kicked out. Even massage the truth? Thanks to early drawings, we know what the base looked like. According to the sculptor's name and some other clues, Venus was definitely dated 130-100 BC.
Dated - the so-called Hellenistic era. That was a problem. It was 200 years after the classic d - the one that the critics loved.
The French tried to hide them. The base 'was lost' before Venus was exhibited in the Louvre in 1821. After the pedestal was tended, the director of the museum stated that Venus was definitely “classical” “not Hellenistic.
And the Louvre backed critics who called Venus a work of the classical Greek genius. They gave her a prime spot in the gallery and insisted that it was certainly the well-known goddess Venus - although she had no label, interpretations of what Venus' missing arms were doing showed up, and the Louvre supported those of who they thought they made Venus look the most important. All of this worked.
Venus had a prime spot in the galleries and became an icon until 1951 when they finally reversed course.
Her unique fame was the result of the Louvre's branding campaign to regain national pride. This story makes her the Venus we know. Maybe the story is why it's still worth seeing today.
OK so a little public service announcement, if you want to have your own Venus de Milo 3D printed I have a link to it in the description below inserted into a really nice model. And I actually finished mine at the local library. Maybe you can too, and don't make the same mistake as me - get yours in pink or lime green.
The period of Venus Transit lasts for about 23 days, i.e. it remains in one zodiac for 23 days and then transits into another house. Venus Transit provides different results in different aspects and affects the physical, social and marital life of a person.
Thanks to Ptolemy and his cronies, everyone thought that the earth was the center of the solar system, with the sun, planets, and even the stars revolving around them on a series of concentric crystal balls. It was a smart idea and explained the movements motion of the planets kind of.
Then in 1543 Copernicus found out that the earth is not the center of the solar system. In fact, it's just one planet in a huge solar system, with objects swirling and whirling around the sun. With the structure of the solar system figured out, and the idea of the crystal ball in the garbage, astronomers still had a great unknown: How big is the solar system? Was it a few million kilometers in diameter or hundreds of millions.
How big is the sun far away is Venus? Astronomers needed some kind of cosmic yardstick to measure anything against. Find one piece of the puzzle and then you could measure everything else in relation to each other. In 1627 Johannes Kepler determined that the movement of Venus was predictable. and the Venus would pass in front of the sun in 1631, probably in the afternoon.
This is known as the 'passage' of Venus. The first rough measurements of the movement of Venus across the Sun were made in 1639 by Jeremiah Horrocks and William Crabtree from two different locations in England. And with these two observations, they were able to calculate the geometry between the earth, Venus, and the sun.
When you remember all of those memories that you push out of your high school geometry, once you have an angle and one side of a triangle, you can figure out all of the other parts of the triangle. Horrocks and Crabtree calculated the distance from the earth to the sun with an accuracy of about 2/3. Not bad considering that prior to that point, astronomers literally had no clue.
Following this observation, the astronomers returned to their telescopes on each Venus transit, refined their calculations and finally agreed on the current distance of around 150 million kilometers. From here on earth we can see some objects happening in front of the sun: Venus, Mercury and the moon. Venus transits are the rarest and occur twice about every 108 years.
Mercury transits happen more frequently, about a dozen times per century. And a transit of the moon, also known as a solar eclipse, occurs on average a couple of times a year. It's all a question of perspective.
When standing on the moon, you may see the earth pass before the sun - a lunar eclipse, while the lunatic would call it an earth transit. We can also see transits in other parts of the solar system, like moons passing planets. For example, if you have a small telescope, you can see when Jupiter's larger moons are moving past the planet from our perspective.
However, one of the questions you may have is why these transits don't happen more often. Why don't we see a Mercury or Venus transit every time they line up with us and the sun. This is because the planets are not oriented at exactly the same angle to the sun.
Planets are tilted at an angle that takes them above or below the sun at different points in their orbit. For example, the orbit of Venus is tilted 3 degrees from the equator of the sun, while the earth is tilted 7 degrees, Venus and Earth are lined up, Venus is either above or below the sun. Are you an ageless vampire or plan to live in multiple robotic bodies for a long time, then you are in luck.
In the year 69.163 there will be a double transit on the solar surface with both Mercury and Venus at the same time. Enjoy while you ponder the horror of your existence.
Once we become a true solar system civilization, there will be even more opportunities for transits. The people who live on Mars will be able to see Mercury, Venus, and even Earth transits in front of the Sun. Neptunians will get bored of seeing them so often. they survive A section of the night sky observing the brightness of thousands of stars.
When a planet passes perfectly right between us and a star, Kepler detects a drop in brightness. When you think about the geometries involved, it's amazing that this happens at all. But the universe is a huge place.
Even if even a tiny percentage of the star systems are perfectly aligned with us, there are enough to discover thousands upon thousands of planets. Kepler has uncovered worlds the size of the earth orbiting other stars, some of which even orbit the habitable zone of their planet. Watching planetary transits is more than just a fun astronomical event, it is how astronomers figured out the size of the solar system for themselves.
And now they are helping us to find other planets orbiting other stars, agree to meet in the year 2117 for the next Venus transit and celebrate this amazing event.

Transits of Venus are so rare because the planet's orbit is tilted just over three degrees from the plane of the solar system. This means that most of the time Venus passes above or below the sun's disk, as seen from Earth. .
Traditional astrology says that women will attract others using the qualities of their Venus sign, while men will attract others using the qualities of their Mars sign. I've found that this is 80% true. Her Venus was in Aries, so 80% of her attractive qualities that others notice right away will be Arian qualities. .
The transit (moving) Venus travels fairly quickly, spending about one month in each sign. The aspects it makes last for about two days, the day before and day of.
However, little detectable water has been found anywhere on Venus, either on its surface or in its atmosphere. Water, like carbon dioxide, is a greenhouse gas. What is NOT a reason for Venus to now be so dry? Venus never had any water because it is too close to the Sun.
Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth. Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon).
If you have Venus in Taurus or Virgo or Capricorn in your birth chart, when you go into flirt mode you tend to act to attract in one or more of the following ways: Earthy. You appear natural, nature-loving, grounded, solid, steady, and stable. You seem comfortable or a calming influence.
If you have either Venus (with feminine energy) in Scorpio or Mars (with masculine energy) in Scorpio, then you're quiet yet intense around someone you're flirting with. You can be mesmerizing and probing, and you won't give attention to anyone except the object of your affection. .
