A fully eclipsed Moon is sometimes referred to as a Blood Moon for its reddish color.
The term, though not scientific is appropos nontheless because it is highly descriptive.
A blood moon is that red-orange appearance of the full Moon during a total lunar eclipse, which occurs when the Earth passes directly between the Sun and the Moon, casting a shadow on it.
Sunlight passes through Earth's atmosphere, which filters out blue light and scatters it, leaving the redder wavelengths to be reflected off the Moon's surface, giving it a copper or rusty red color.
It may further be referred to as:
A total lunar eclipse
A lunar tetrad
The Full Moon in October
While an interesting sidebar, the appearence is purely that — the way it looks. It is not going to involve any actual blood, detrimental effects, nor harm to the solar system.
So I hope you can take a moment and view the astronomical show.
