The visible area of the total eclipse
coincides with the "Super Moon"+ "Wolf Moon", so many media have named it "Super Blood Wolf Moon" and NASA even named it "Super Moon Trilogy".
The whole eclipse process sketch
However, in fact, this so-called "Super Blood Wolf Month" ( China can not see ), and astronomically related only to the "Blood Moon" or the total eclipse of the Moon, we will go into detail next.
total lunar eclipse
When the moon, the earth and the sun are completely in a straight line, the earth between the sun and the moon, and the earth shadow completely blocks the sunlight shining on the surface of the moon, thus forming a total lunar eclipse. Total lunar eclipse is a very common astronomical phenomenon , occurring 70 to 80 times per century.
When total lunar eclipse occurs, the moon appears dark red or bronze , which is called "Red Moon" or "Blood Moon". The reason why the moon appears this color, not all black, is that when a total lunar eclipse occurs, the longer wavelength red light can penetrate the earth's atmosphere and refract to the surface of the moon, while other short-wave colors of light are scattered and absorbed, and can not shine on the moon.

"super moon" is a new term, which refers to the phenomenon that the moon is near the perigee when occurs at the full moon. Super Moon was not proposed by astronomers, but by a < strong > astrologer in the United States in 1979, and gradually spread to the public.
Because the orbit of the moon around the earth is not a standard positive circular orbit, but an elliptical orbit, although the average distance between the earth and the moon is 384,000 km, the distance between the earth and the moon at apogee and perigee is different. The distance between the earth and the moon at apogee is more than 400,000 km, while that at perigee is less than 36,000 km. Ten thousand kilometers.
The orbit of the moon around the earth
According to the perspective principle of object's "near-large-far-small", the full moon at perigee looks about 14% larger than the full moon at apogee (visual diameter), and its brightness is about 30%, which is called "supermoon". In addition, the Apogee Full Moon has a name called "Micromoon".
The comparison between super-moon and mini-moon
The super-moon happened during the daytime in our country, so the public could not see it (the moon was under our feet at this time, under the horizon). But there is no need to regret that on February 19 (Lantern Festival), another round of "Super Moon" will also illuminate the night sky, adding a festive atmosphere to the festival. And this time on February 19, it looks bigger and brighter because it's closer.

about this "Wolf Moon", not the moon looks like a wolf, but according to a "American farmer Yearbook" (Farmers'Almanac) (feel very earthy not Tucao name, this book is the sauce purple drops) record, the full moon of the month of the moon is Known as Wolf Moon , there are also rumors that wolves always howl hungrily outside villages at the first full moon in January.
In fact, this "wolf moon" is not very big. The following is used to continue to unveil the nicknames or nicknames of the full moon in the American Old Farmer's Yearbook.

full moon in September: "Harvest Moon"or"Full Corn Moon"full moon in October :"Hunter's Moon"(Hunter's Moon) or"Blood Moon"/"Sanguine Moon" full moon in November: "Beaver Moon"(Beaver's Moon) Or "Frosty Moon"
