Why the moon is a little reddish and very low

This situation mostly occurs when the moon has just risen and is about to set or lunar eclipse, because the angle of the moon is low at this time, the atmosphere is relatively dense, and the obstruction effect on light is relatively large, and among all visible light, red light has the strongest penetration ability because of the longest wavelength, and most of the rest of the light is obstructed by the atmosphere, so it looks red, it is precisely because of this characteristic of red light that red lights are used as warning lights.

The moon itself does not emit light or change color, and the reason why it turns red is mainly due to changes in the sun. After the short wavelength of blue light and violet light in the sunlight is scattered and absorbed by the atmosphere, the red and orange light with longer wavelengths will be refracted through the atmosphere to the surface of the moon, and then reflected to the surface of the earth again, and the moon can be seen turning red in human vision. Moon.

The Moon is a sphere and its orbit around the Earth is elliptical, so the distance between the Moon and the Earth is not constant, and when the Moon is closest to the Earth, the Moon is large and round. The atmosphere contains a large amount of dust, and the dust and clouds block the moonlight, and only the penetrating red light can illuminate it, so the moon appears red.

The Moon is a spherical celestial body that orbits the Earth and is also the only natural satellite of the Earth. In Chinese, it is commonly known as the moon or moon, and in ancient times, it was also called Taiyin, Xuantu, Chanjuan, and Yupan. The Moon is the fifth-largest moon in the solar system, with an average radius of about kilometers, which is equivalent to times the radius of the Earth; The mass is close to kilograms, which is twice that of the Earth.

The surface of the Moon is covered with craters formed by the impact of small celestial bodies. The average distance between the Moon and the Earth is about 10,000 kilometers, about 30 times the diameter of the Earth.

This situation mostly occurs when the moon has just risen and is about to set or lunar eclipse, because the angle of the moon is low at this time, the atmosphere is relatively dense, and the obstruction effect on light is relatively large, and among all visible light, red light has the strongest penetration ability because of the longest wavelength, and most of the rest of the light is obstructed by the atmosphere, so it looks red, it is precisely because of this characteristic of red light that red lights are used as warning lights.

The moon has many magical astronomical phenomena and is a satellite that has a significant impact on the earth, and mankind has never stopped exploring the moon. As the progress of human exploration of the moon progresses, it is believed that in the near future, scientists can unravel more mysteries about the moon, and these mysteries will also have a new impact on human life.

Some redness of the moon is caused by changes in cloud cover, and the thickness of the clouds is one of the main reasons for the change in the color of the moon, not only because of the change in cloud cover, but also because of other factors, such as the humidity of the atmosphere.

Because the moon angle at this time is smaller, the atmosphere is denser, and the blocking effect on light is greater. Of all the visible light, red light has the longest wavelength, so it has the strongest penetrating ability, and most of the rest of the light is blocked by the atmosphere, so it looks reddish.

Red light has a long wavelength and strong penetrating power, and after the atmosphere at high altitude absorbs all the violet, blue, green, and yellow light, only red light can penetrate the atmosphere. In urban areas, when the moon first crosses the horizon, there is more dust in the air, and the dust absorbs the blue-violet light, leaving the red light, and the moon turns red.
