The moon orbits the Earth every 27.32 days, or about once a month. In astronomical terms, transit occurs when the moon or another celestial body passes over a particular point.
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 Copernicus found out in 1543 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. 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 every 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 few times a year. It's all a question of perspective.
When standing on the moon, you may see the earth go by before the sun - a lunar eclipse, while the lunatics 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 pulling 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 be more than just a fun astronomical event, they are 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.

Natal house is the sign where a planet was originally placed during your time of birth. If Moon was placed in Aries in your personal horoscope, then Moon transit through that sign (Aries) is called Transit Moon through Natal 1st House and remaining houses are counted clock-wise.
Transiting Moon conjunct your natal Moon. This marks the beginning of a new emotional cycle for you that will last one month until this conjunction occurs again. If the Moon is the Lord of your first HouseYour emotions dictate your actions and level of willpower during this period of time.
When the Sun moves across the sky, and rises a little bit east or west than it did the day before, that is a transit. The transit of the Sun. When the Moon is Full and shines brightly in the night sky, or when the Moon is a tiny sliver of a crescent waxing moon, that is a transit. .
Transiting Moon lasts a few hours at most and affects mainly moods and feelings, not always consciously, according to the planet, sign and house being transited. Transiting Mercury is at its peak for only a day or two. A useful time for helping with backlogs of correspondence, making short journeys or visits.
THE PROGRESSED MOON AS A TIMER OR TRIGGER
In the sky the Moon takes about a month to complete a cycle; when seen through progressions, it slows to almost 30 years, taking about 2 ? years through each house, several months in contact with any natal planet. .
The Moon In Scorpio: Personality
While Scorpios appear calm on the outside, on the inside they are a raging sea of emotion and intensity. This is what makes them appear so mysterious. The Moon in Scorpio magnifies their allure. They are incredibly intuitive and can read people like a book, while they remain obscure.
When the Moon returns to the positionor even just the signit was in at your birth, this is called the Lunar Return, and it happens about once a month. Your emotions and intuition will be heightened and you might feel a lil bit moody.5 2020 .
When the Moon is in Leo
When the Moon is moving through Leo, regardless of how you normally feel, you will have a stronger desire to let others how you feel. You'll be more apt to tell people that you love them, or express your appreciation for them. .
