Because the moon comes between the sun and Earth, casting the moon's shadow on Earth.
Since the Moon is quite a bit smaller than Earth, the Moon's shadow can only cover part of Earth's surface. In that case, the people in that shadow will see a solar eclipse.
A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light and casting a shadow on Earth. A lunar eclipse happens when the Earth passes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.
I believe you mean the lightest part of Earth's shadow casted upon the moon and the answer to that would be: The lightest part of Earth's shadow upon the moon is called the penumbra. In fact any shadow is divided between that totally blocked (umbra) and partially blocked by the light source (penumbra) so the Penumbra can indeed be the moons partial shadow on the earth during a partial or total solar eclipse
Penumbra.
There are two parts to the Earth's shadow. The dark narrower part is the Umbra (from Latin for shadow). The lighter part is called the Penumbra (from Latin, pane umbra - almost a shadow)
When you are in the moon's shadow during a solar eclipse, it is called the umbra. This is the central, darkest part of the shadow where the sun is completely blocked by the moon. Outside of the umbra is the penumbra, where the sun is only partially blocked, resulting in a partial eclipse.
its part of the roation and orbit of the earth. its an eclipse.
No, it's only in shadow when the part we can see is lit.
-- During a lunar eclipse, the moon is in Earth's shadow. -- During a solar eclipse, a small part of Earth is in the moon's shadow. -- In order for either of these to happen, the Sun, Moon, and Earth must be all lined up. -- New Moon and Full Moon are the phases when Sun, Moon, and Earth are all lined up.
Lunar Eclipse. It happens only when the Moon surpasses a part of the Earth's shadow.
It is called a solar eclipse. And when the Earth casts a shadow on the moon, it is called a lunar eclipse.
During a lunar eclipse, the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall directly on the Moon. The Earth's shadow is large enough to cover the entire Moon due to its size and the distance between the Earth and Moon. Conversely, during a solar eclipse, the Moon is positioned between the Earth and the Sun, casting a smaller shadow on the Earth. The Moon’s shadow is much smaller because it is significantly smaller in size compared to the Earth, leading to only a partial coverage of the Earth's surface.
