Most of the names for full moons are actually derived from the Native Americans. In this particular example, the “snow” moon earned its name from the time of year it appears at, given “February’s typically cold, snowy weather in North America” the UK’s Royal Museums Greenwich explains.
In an ironic contrast, Native Americans also call it the “first flower moon” because Spring is usually just around the corner.
The other interesting thing about this full moon is that it will show itself when the planet is at its farthest distance from Earth. As a result, this full moon will be smaller and dimmer than a regular full moon and thus earns itself a third title of “micro moon.”
