How does a lunar eclipse happen?

lunar eclipse It is a phenomenon in which the Sun, the Earth and the Moon orbit on the same plane. There is an Earth in the middle between the Sun and the Moon. How the moon orbits through the shadow of the Earth Observers on Earth will see the moon gradually dented until it enters the entire shadow, creating a total lunar eclipse. and he began to see the moon bruised once more as the moon moves away from the earth

The shadows of the Earth that cover the space are divided into two types: Penumbra Shadow, which is the outermost shadow, when the moon is in the fang, this part has a slight decrease in brightness, and the Umbra Shadow, a shadow intimate dark. When the moon enters the fang, this part will form a dark dent. Therefore, the types of lunar eclipses can be classified as follows:

type of lunar eclipse

  • Total Lunar Eclipse (Total Lunar Eclipse) The entire moon moves into the shadow of the Earth. The moon will be seen in orange or brick red.
  • Partial Lunar Eclipse (Penumbral Lunar Eclipse) The moon partially crosses the Earth’s shadow. will see the moon seem concave
  • Lunar eclipse of penumbra The moon passes in the terrestrial penumbra. without going through the shadows I still see the full moon but the brightness will decrease It is difficult to notice the change.

Why is the moon “red” during a full lunar eclipse?

During a total lunar eclipse, when sunlight passes through the Earth’s atmosphere. Blue light with a shorter wavelength is completely dispersed from the atmosphere. Only red light with a longer wavelength is refracted to hit the moon’s surface. therefore the moon is seen in red

3 reasons to watch “The total lunar eclipse in the Thai sky”

(The time of the total eclipse observed in Thailand is approximately 17:44 – 18:41, a total duration of 57 minutes.)

Then the moon will move from the shadow into the penumbra of the Earth. a partial lunar eclipse phenomenon will see the moon partially dented and when the moon enters the penumbra of the whole world it will occur as a penumbral lunar eclipse See the full moon with a slight decrease in brightness Before the end of the phenomenon at 20:56, when the moon orbits around the entire shadow of the Earth.
