It was 6° F outside, but I persisted. We had a spectacle of a blood moon coupled with a lunar eclipse.
The etymology of the event comes from the proximity of the moon relative to the earth. Since orbits are elliptical and not circular, the objects in motion become closer to one another than at any other point in their trajectories. In this case, the moon came 30,000 miles closer to the Earth and appeared 30% brighter than normal and so we get a “Supermoon.”
The blood moon comes from the copper/red color the moon gives off during the eclipse.
The “wolf” part has less to do with werewolves and more to do with the Native American name for the January full moon.
The lunar eclipse part comes from the earth being sandwiched between the moon and the sun. When this happens, earth casts a shadow over the moon; whereas during a solar eclipse, the moon (sandwiched between the earth and the sun) blocks light from the sun.
