The Moon does not orbit directly in line with the orbit of the earth around the sun. The orbit has a slight tilt, know as inclination, of about 5 degrees. Also, the earth does not rotate exactly exactly aligned with the sun or the moon. And each rotation has a different speed or period. So there is only two points every year when a solar eclipse will occur somewhere. Every year there will be at least two solar eclipses, although when the Moon catches the point at just the right time there can be up to three eclipses in the same season, but in different places. This only happens once every 233 years or so.

∙ 14y agoThe Earth orbits around the Sun in a flat plane called the "ecliptic". The Moon orbits around the Earth in a flat plane as well, but it is tilted about 5% from the plane of the Earth's orbit.
So most of the time when the Moon gets in between the Earth and the Sun, it isn't EXACTLY between; the Moon is just a little bit above or below the ecliptic. When the Moon is New just as the Moon's orbital plane is passing through the plane of the ecliptic, we have eclipses; generally two per year.
Normally there is a lunar eclipse 2 weeks before (or two weeks after) every solar eclipse.

Why do you suppose an eclipse does not occur every time eart is between the sun and the moon?
The orbit of the moon is tilted by about 5 degrees so this means there is not an eclipse at every New of Full moon.
How do the relative motions of the earth sun and moon lead to eclipses?
The Earth goes round the Sun in an orbit, while the Moon travels round the Earth. If those orbits were in exactly the same plane we would have a solar eclipse at every new Moon and a lunar eclipse at every Full Moon. The Moon's orbit is at an angle to the Earth's, so at most full/new moons the Moon is above or below the plane of the Earth's orbit (known as the ecliptic). But if the Moon is crossing the ecliptic at full or new moon, we get an eclipse.
When the moon blocks the sunlight from reaching the earth?
This named a 'Solar Eclipse'. The is also a 'Lunar Eclipse' , when the Earth blocks the sunlight from a full moon. The Moon orbits the Earth once every 29 days. The lunar orbit and the solar orbit are not co-planar. . They are angled at about 2 degrees. Consequently, we do neither see a Solar Eclipse at every New Moon, nor a Lunar Eclipse t every Full Moon.
Why don't Eclipse occur during every full moon or new moon phase?
It is because the moon's orbit is tilted with respect to the ecliptic by about five degrees, meaning that at most new or full moons, the moon passes above or below the Earth's shadow, preventing an eclipse.
What book is after new moon?
Eclipse
Is there an eclipse every time a new moon occurs?
no
What type of moon is during a solar eclipse?
We see solar eclipses only during New Moon, but not every New Moon is accompanied by a solar eclipse.
Is a solar eclipse at every new moon?
well no not at all
Does a solar eclipse occur on every new moon's/moon day?
No, it doesn't take place on every new moon day but yes, on some of them.
Why do you suppose an eclipse does not occur every time eart is between the sun and the moon?
The orbit of the moon is tilted by about 5 degrees so this means there is not an eclipse at every New of Full moon.
How many times in one lunar cycle could there possible be a solar eclipse if the earth and moon were in orbits that were perfectly leve?
If the orbit of the Moon was level with the orbit of the Earth around the Sun, there would be a solar eclipse at every new moon, and a lunar eclipse at every full moon.
When do solar eclipses take place?
A solar eclipse can only happen at new moon - but they don't happen at every new moon.
Why do you not have an eclipse every time we have an new or full moon?
The moon's orbit relative to the earth is tilted 5 degrees.
What is the relation of the orbit of the moon to the orbit of the earth?
The moon's orbit is inclined about 51/2 degrees relative to the plane of the Earth's orbit. For one thing, this explains why we don't have a lunar eclipse at every Full Moon, and a solar eclipse at every New Moon.
What is the difference between the lunar eclipse and solor eclipse?
In a lunar eclipse the Earth is in the middle and blocks the Sun's light from the Moon, so that happens always at Full Moon but not every time. A solar eclipse has the Moon in the middle so it happens at New Moon, but not every time, and the Moon is not big enough to shadow the whole Earth so a solar eclipse is seen only in a strip across the Earth's surface.
What is the moon is on the earth shadow?
This is an eclipse of the moon.
Would a solar eclipse happens at full moon or new moon?
solar eclipse happen at full moon or new moon
