A lunar eclipse occurs when the Moon enters the Earth's shadow. A solar eclipse occurs when the Moon's shadow falls on the Earth. They do not happen every month because the Earth's orbit around the sun is not in the same plane as the Moon's orbit around the Earth.
When is eclipse Tonight?
This eclipse is visible from northern and northeastern North America, beginning at 4:12 AM EDT and ending at 9:11 AM EDT. The time of maximum eclipse varies by location. Note that this is an annular eclipse; the Moon will never fully obscure the visible surface of the Sun—at maximum eclipse, an “annulus” (ring) around the Sun will still be visible.
How often are lunar eclipse?
- The lunar (synodic) month: the time it takes from one New Moon to the next.
- The anomalistic month: the time it takes from Moon perigee to perigee, the point of the Moon's orbit closest to Earth.
- The draconic month: the time it takes from one lunar node to another. Also called the nodical month, it lasts, on average, 27.212220 days ( i.e. ...

Can you draw the Moon on the same paper?
If you were to draw a little Earth in orbit around a little sun on a piece of paper, then you would not be able to accurately draw the Moon's orbit on that same piece of paper. Sometimes the Moon will be above the paper, other times below it.

What is the angle of the Moon?
This is the plane of the ecliptic, and all of the planets are arranged in that disk. But the Moon is on another disk, which is inclined at an angle of 5.14 degrees. So, if you follow the orbit of the Moon as it goes around the Earth, sometimes it’s above the plane of the ecliptic and sometimes it’s below.

Why do we see red sunsets?
It's the same reason we see red sunsets here on Earth – the atmosphere filters out the green to violet range of the spectrum, letting the red light pass through. The Earth's atmosphere refracts the sunlight so that it's bent slightly , and can illuminate the moon during the greatest eclipse.
What is the angle of the moon?
This is the plane of the ecliptic, and all of the planets are arranged in that disk. But the moon is on another disk, which is inclined at an angle of 5.14 degrees. So, if you follow the orbit of the moon as it goes around the Earth, sometimes it's above the plane of the ecliptic and sometimes it's below.
Is the Moon lined up with the Sun?
If the sun, Earth and moon were truly lined up perfect, this would be the case. But the reality is that they're not lined up. The moon is actually on an in clined plane to the Earth. Imagine the solar system is a flat disk, like a DVD.

How long does it take for the Moon to orbit the Earth?
The moon takes about a month to orbit around the Earth. If the moon orbited in the same plane as the ecliptic – Earth’s orbital plane – we would have a minimum of two eclipses every month.

What is the ecliptic of the Moon?
There might be some unfamiliar words in this video, including ecliptic and node. The ecliptic is the plane of Earth’s orbit around the sun. The moon’s orbit is inclined to the plane of the ecliptic. The nodes are the two points where the moon’s orbit and the ecliptic intersect.
How long does it take for the moon to return to its node?
But the moon returns to its node a good two days earlier than that, or in about 27.2 days.
