A lunar eclipse happens when the Earth passes between the moon and the sun. Lunar eclipses cast a shadow on the moon due to the Earth's location. From the perspective of the moon, the Earth completely blocks the sun.Continue Reading
According to MrEclipse, there are roughly 1 1/2 full lunar eclipses each year, although the number can be as low as zero or as high as three. There are both full and partial eclipses each year, and there are usually many more partial lunar eclipses per year than full. The angle of the moon's orbit makes it impossible for there to be full or partial lunar eclipses every lunar month.
The shadow of a lunar eclipse does not typically completely black out the moon. The moon is still visible even during full lunar eclipses, but its color changes, and it is less visible than it is before and after the event.
It is also much easier to see a lunar eclipse than a solar eclipse due to how close the moon and Earth are to one another. It is safe to view a lunar eclipse since the light from the moon can not damage a person's eyesight like the sun can, even during a solar eclipse.Learn more about Our Moon
The moon appears bright because the side visible on Earth reflects the light from the sun. As the moon and the Earth move around their respective orbits, different portions of the moon are visible to people on Earth, depending on the angle at which the light hits the moon and reflects back to Earth. The moon reflects back about 12 percent of the light from the sun that hits it.Full Answer >
Crescent moons happen when Earth, the sun and moon are positioned in a way that only shows a portion of the reflected light on the moon. The result is a crescent-shaped light pattern.Full Answer >
The moon is not visible to observers on Earth during its new moon phase, when the moon is located on the same side of Earth as the sun. During this phase, the portion of the moon that is illuminated by the sun faces entirely away from the Earth.Full Answer >
According to NASA, a full moon technically only lasts for the moment when the Earth is directly between the sun and the moon. However, full moons appear to last for approximately three days.Full Answer >
