Why is the Moon reddish copper colored at the time of the lunar eclipse 5

One time... Eh, because it's a lunar eclipse.

That's because during a total lunar eclipse, sunlight is refracted by the Earth's atmosphere and projected onto the moon's surface, giving the moon a reddish-copper color. In addition, you must know that sunlight is composed of seven colors of light, with red having the longest wavelength and the strongest penetrating ability.

In fact, during a total lunar eclipse, the color is also related to the weather, and the color is different between cloudy and less cloudy.

Lunar eclipses are the cause of the Red Moon:

When a total lunar eclipse occurs, when the moon, the earth, and the sun are completely in a straight line, when the sunlight passes through both sides of the earth, the thick atmosphere of the earth absorbs the violet, blue, green, and yellow light, leaving only the red light with the longest wavelength to penetrate and be refracted by the atmosphere to the moon, so during the total lunar eclipse, you can see the moon in the shadow of the earth showing red.

A lunar eclipse, also known as a lunar eclipse, is an astronomical phenomenon in which the part of the moon that could have been illuminated by the sun's rays cannot be partially or completely illuminated by direct sunlight when the moon moves into the earth's shadow (the shadow is divided into umbra and penumbra), making it impossible for observers on the earth to see the ordinary moon phase.

When a lunar eclipse occurs, the Sun, Earth, and Moon happen to be or almost in the same straight line, so the eclipse must occur on the night of the Full Moon (lunar calendar.

Ten. Five, ten.

6. or 17), as the Shuo Wen says, "the solar eclipse is the new year, and the lunar eclipse is the hope."

The Earth's shadow is located in the Earth's orbital plane (ecliptic plane), which does not coincide with the lunar orbital plane (white plane), and the intersection angle of the yellow and white planes is about 5 degrees. During most Full Moons, the Moon is not in the ecliptic plane, but is either north or south, not in the Earth's shadow, so not every Full Moon eclipse occurs. Lunar eclipses occur at least twice a year around the world.

During a total lunar eclipse, the moon is dark red. A total lunar eclipse is an astronomical term, a type of lunar eclipse, when the moon, the earth, and the sun are completely in a straight line, the earth is in the middle, and the entire moon walks into the shadow of the earth, and the surface of the moon turns dark red, forming a total lunar eclipse. For example, on October 8, 2014, a "total lunar eclipse" was staged in the sky, and the moon did not disappear, but became a mysterious and beautiful "red moon".

Total lunar eclipse recordFor example, on October 8, 2014, a "total lunar eclipse" was staged in the sky, and the moon did not disappear, but became a mysterious and beautiful "red moon". The total lunar eclipse began at 17:14 on the evening of the 8th, and lasted about 3 hours and 20 minutes from the initial waning to the reunion. On the night of April 4, 2015, there was a total lunar eclipse in the sky.

The time of the initial loss was 18:15 on the 4th; The time of the meal is 19:54; The time of eclipse is 20:00; The time of light is 20:06; The time of the reunion is 21:45.

Among them, the most exciting total eclipse lasted 12 minutes, which is also the shortest total lunar eclipse in 134 years. In 2018, China entered a period of total lunar eclipses, with total lunar eclipses occurring on the night of January 31 and the early morning of July 28.
