So you know what a blood moon is? It’s when the moon moves into the shadow of the earth (a total lunar eclipse), which causes the moon to grow fairly dark and at the same time pretty reddish as the image below shows.
Next, do you know what a supermoon is?
The moon has a slightly elliptical orbit around Earth. Sometimes full moons are further away and appear slightly smaller from Earth. Sometimes full moons are slightly closer to us and they appear larger. When the latter happens it’s a super moon.
A super blood moon simply means when the moon is slightly closer to Earth because of it’s elliptical orbit and it passes into the earth’s shadow. The last one was on January 20, 2019, and will be the only one in 2019.
The next total blood moon lunar eclipse won’t be until May 26, 2021, but it will not be visible from the United States or North America. North and South America won’t see a total lunar eclipse again until May 16, 2022. It will not, however, be a super moon at the same time. For that you’ll have to wait about 19 years.
