Supermoon 2023: Witness the Majestic Lunar Event

 An event known as a Supermoon occurs when the moon is at its nearest approach (perigee) to Earth concurrently with a full moon. A Supermoon is particularly fascinating for its viewers as it provides an opportunity to observe and learn. The moon's orbit around the Earth is elliptical, meaning it oscillates between closer and further distances from our planet. At its farthest point (apogee), the moon is approximately 405 thousand kilometers away. However, when the moon reaches perigee, its closest point, it is about 363 thousand kilometers from Earth. A full moon at perigee appears slightly larger and brighter than a standard full moon, resulting in a Supermoon.

Origin of the Term

The term "Supermoon" was first used in 1979 and is commonly employed to describe an astronomic event known as a "perigee full moon." This event is characterized by a full moon that coincides with the moon's closest approach to Earth. But what sets a Supermoon apart? The moon's orbit shape fluctuates over time due to the gravitational impacts of the Sun and other planets within our solar system.

Furthermore, it's worth noting that a perigee full moon can cause more pronounced high and low tides. These extremes are amplified due to variations in the moon's gravitational pull on the Earth's diameter. When the moon is closer, the Earth's diameter is slightly larger than the Earth-Moon distance, causing the moon's gravitational attraction on the oceans and the whole Earth's crust to vary. On August 1, 2023, the moon will rise around 8:45 p.m. in the east and will be visible throughout the night. The exact timing may vary depending on the viewing location and potential obstructions. Whether you observe it with binoculars, a telescope, or the naked eye, the Supermoon promises to be an intriguing spectacle. Here's to clear skies and great observations!
