How would solar eclipses be different if the moon were twice as far from the earth?

At that time, total solar eclipses will not happen; they will be a thing of the past. That time is coming; the moon is very slowly moving farther and farther from earth.
There would be no Total Solar eclipse if the moon were twice as far from the earth, the reason is that the earth would never fall in the umbra, which is the place where sunlight is completely blocked. Even to this day only a small portion of our earth will ever get to see a total solar eclipse. however a very small portion of earth located right behind the shadow will see a annular solar eclipse, in which a ring of sunlight surrounds the disk of the moon. The ring would be much bigger if the moon was twice the distance.

Does a Solar eclipses occur each month at different locations on Earth?
No, solar eclipses happen about twice a year. (Sometimes instead of one "real" eclipse, we get two "partial" eclipses.) You can look up the dates and locations of solar eclipses starting with the year 2000 BC and going to 3000 AD on the NASA Eclipse web site (linked below).
How would solar eclipses be different if the Moon were twice as far from EarthWhy?
If the Moon were at twice its orbital distance, there would be no total solar eclipses, only annular ones. This is because the umbra, the complete shadow of the Moon, would not reach to the Earth. I would have to run the numbers to be certain, but I suspect that there would be no total lunar eclipses, either, for the same reason. However, you would probably be able to see the shadow of the Earth passing across the face of the Moon!
How often do total solar eclipses occur?
About twice a year.
Why does a solar eclipse occurs only a few times a year?
It does not. There are generally two solar eclipses and two lunar eclipses each year. Because the alignment of the Earth, Moon and Sun is rarely precisely right, we sometimes get two partial eclipses instead of a single total eclipse, but on average, two per year.
What are eclipes?
Eclipses are shadows. A lunar eclipse is the shadow of the Earth on the Moon. A solar eclipse is when the Moon's shadow is on the Earth. Because the Earth is both spinning on its axis and orbiting the Sun, and because the Moon orbits the Earth at a bit of an angle to the ecliptic (the plane of the Earth's orbit) we only get eclipses when the Sun, the Earth and the Moon line up in a straight line. This happens about twice a year.
In ancient times the Moon was farther from Earth and solar eclipses would appear more often?
The Moon has not receded from the Earth by any visible amount since the dawn of human history. However, millions of years ago, the Moon was closer to Earth, not farther away. Eclipses would have still appeared about twice a year, but some of the partial or annular eclipses might have been total, way back when.
When do solar eclipse occor?
The Earth goes around the Sun, and the Moon goes around the Earth. Sometimes, the Earth gets just exactly in between the Sun and the Earth, so that the shadow of the Moon hits the Earth. When that happens, we have a solar eclipse. There are generally two solar eclipses each year, but because the area on Earth where the Moon's shadow lands is so small, it's rare to see one. Lunar eclipses also occur twice a year, but because they happen on the Moon, everybody on the night side of the Earth can see each one.
How often is there a full solar eclipse?
There are generally two solar eclipses and two lunar eclipses each year. Sometimes there are more, or fewer; for example, in 2011, there will be no solar eclipses at all. The maximum possible number is 5 per year, which happens very infrequently.
How often will a solar eclipse happen?
Solar eclipses happen about twice a year, on average. Depending on the precise alignment of the Sun, Moon and Earth, we sometimes get two partial eclipses instead of one total or annular eclipse. However, because a solar eclipse affects a very small area of the Earth, it's rare to have two solar eclipses in the same area less than about 60 years apart. However, there will be a total eclipse with a path of totality across the USA from west to east in 2017, and a total eclipse that will track from southwest to northeast in 2024. The paths cross at Carbondale, IL, and within about 30 miles of there one would experience two total solar eclipses only 7 years apart.
Why are you less likely to see a total solar eclipse?
Solar eclipses and lunar eclipses each happen about twice a year. However, a lunar eclipse can be seen from the entire night-side of the Earth, while a solar eclipse is visible across only a narrow path across the planet. And since 3/4 of the Earth is covered by water, many eclipses are never seen by anybody! For example, the next solar eclipse is on July 11, 2010. The path of totality begins deep in the South Pacific Ocean, and covers a few scattered atolls in French Polynesia, Easter Island, and the southern tips of Chile and Argentina.
What is the astronomical event that happens twice a year when the earth's axis is inclinded neither towards?
lunar eclipses
When might an eclipse happen?
Lunar eclipses happen about twice a year at the full moon. Solar eclipses happen about twice a year at the new moon.The link below to the NASA Eclipse Site lists details about every eclipse from 2000 BC to 3000 AD.
