What do you call a red moon?

Question

What do you call and what causes the moon to appear red?

Answer 1

A red moon means there is a high concentration of particles in the air, such as dust and smoke. These particles “scatter” away the short and intermediate wavelengths of light (violet, blue and yellow), leaving only the longer wavelengths (orange and red) to reach our eyes. A red moon does not mean there is a change coming in the weather.

During a total lunar eclipse, the Earth's atmosphere creates two very noticeable effects. The first is that it causes the moon to appear red. This is because the atmosphere scatters sunlight around Earth; shorter wavelengths are scattered more easily, and so do not pass all the way around Earth with nearly as much intensity as the shorter, redder light. This effect hints at the second, which is that the atmosphere acts as a lens to amplify the light that would reach the moon.

Answer 2

You call a red moon, a red moon, there really isn't a name for it.

A red moon is caused by a large amount of obscuring particles in the atmosphere, for instance, volcanic ash or ash from wildfires.

Answer 3

It's just the moon.  Like others said, it can be caused by junk in the air. Like the sun, it usually appears red at he horizon.
