There will be a full moon on Saturday dubbed “the Supermoon.” Glaring at a full moon, while it casts its light across the night sky is truly aesthetical and even romantic. It’s a sight worth viewing anytime.
Moreover, a Supermoon has a scientific explanation, even though the use of the term is not appealing to all scientists. The Supermoon, scheduled for Saturday night, takes its place among other two astronomical events that happened this summer – the Blue Moon and the Perseid meteor shower.
This year there will be three Supermoon, the first one will appear on Saturday, August 29th. The other two Supermoons will occur on September 28th and October 27th. The one happening at the end of next month will be the closest and largest Supermoon, and it will coincide with a lunar eclipse, moreover, a total eclipse of the moon.
September’s full moon is also known as the Harvest Moon. It gained this name as it allows farmers to gather their crops and bring in their harvest, as a result of the Earth being more illuminated at night.
Astronomers use the term perigee to refer to the phenomenon, as it seems it approaches the Earth more than other times, while its closest point is named perigee. When it happens to be a full moon, the more common term “Supermoon” has been coined.
To be more precise, the perigee is the antonym of apogee, the latter meaning the moon is farthest from Earth. So, the Earth’s natural satellite’s orbit is elliptical rather than perfectly circular, and this, sometimes, leads to the perigee and apogee.
Furthermore, the perigee will imply a distance of approximately 223,690 miles (360,000 km) from the Earth to the moon, and, as a consequence ocean tides get stronger.
But what “full moon” actually means is the event when the Earth, the moon and the Sun are all lined up, whereas the Earth’s in the middle. As seen by us, the moon is entirely illuminated. So, the full moon happens when it’s situated expressly opposite the sun.
NASA stated that a Supermoon is 30 percent brighter and 14 percent closer to the Earth’s surface, in comparison to regular full moons.
You can observe this rare phenomenon on August 29th with the naked eye, or you could use binoculars if you want to observe the moon’s surface better, while spotting craters and plains.
