Tonight, sky gazers will have the opportunity to witness a celestial phenomenon known as the “micromoon,” which is the smallest full moon of the year. While it may appear smaller in size, this optical illusion is due to its position in relation to Earth. Let’s delve into the fascinating details of February’s micromoon and uncover the origins of its name.
The term “micromoon” refers to a full moon that occurs when it aligns with apogee, the farthest point in its orbit from Earth. In contrast, a “supermoon” takes place when a full moon coincides with perigee, the closest point in its orbit to our planet. According to NASA, this month’s full moon is the smallest appearance of the moon in 2022. However, it’s important to note that the moon is not actually shrinking; its size appears smaller due to its distance from Earth.
February’s full moon is commonly referred to as the “snow” moon, paying homage to the heavy snowfall that typically blankets the winter season. The name “snow” moon has its roots in Indigenous naming traditions associated with the changing seasons. The Farmer’s Almanac explains that Captain Jonathan Carver, who interacted with the Naudowessie (Dakota) tribe in the 1760s, documented their use of the term “Snow Moon” for this time of year. He noted that more snow tends to fall during February compared to any other winter month.
Interestingly, this February has deviated from the usual weather patterns in Michigan, experiencing near-record highs and minimal snowfall. Despite this anomaly, the name “snow” moon remains a testament to the historical significance of this lunar phase.
The full moon officially began at 7:30 a.m. on Saturday, according to the U.S. Naval Observatory. On Friday, sky watchers could observe a waxing gibbous moon, illuminated at an impressive 99%. As we enter day 15 of the current lunar cycle, the moon is positioned over 250,000 miles away from Earth. NASA explains that the lunar cycle repeats approximately once a month as the moon orbits our planet in an elliptical path.
As we bid farewell to winter, this micromoon also marks the last full moon of the season. The next full moon will grace the night sky on March 19, following the Spring Equinox. So, make sure to take a moment tonight to appreciate the beauty and wonder of February’s micromoon, as it silently illuminates the darkness with its serene glow.
