This Wednesday, the celestial event known as the Supermoon will occur, making the Moon appear larger and brighter than usual. This phenomenon arises due to the full Moon coinciding with its closest approach to Earth. On this occasion, the Moon will be approximately 356,833 kilometers away, significantly closer than its average distance of about 380,000 kilometers.
Understanding the Supermoon
The Supermoon effect will cause the Moon to appear about 5.7% larger and 11.7% brighter than its standard appearance. While this may generate excitement on social media, astronomers caution that the event is not as dramatic as it sounds. Florent Deleflie, an astronomer at the Paris Observatory, emphasized that for those who are attentive, it can be an interesting occurrence, albeit not a spectacular one.
Key Details About the Supermoon
- Event Date: This upcoming Wednesday.
- Distance from Earth: 356,833 km.
- Average Distance: Approximately 380,000 km.
- Size Increase: 5.7% larger visually.
- Brightness Increase: 11.7% brighter.
- Future Distance: 406,691 km in 15 days at apogee.
Deleflie explained that the Moon’s orbit is elliptical, meaning its distance from Earth varies throughout the month. When the Moon aligns perfectly with the Earth and the Sun, it creates the full Moon, but its proximity adds to the Supermoon appearance.
Perception of the Moon Size
Atmospheric refraction affects how we perceive the Moon. When the Moon is low on the horizon, nearby objects such as trees or buildings create an illusion of increased size. In contrast, when it is high in the sky, there are no reference points to compare its size, making it appear smaller than when it is near the horizon.
Stargazers can also look forward to spotting Jupiter and Saturn in close proximity to the Moon during this event. Both planets will be visible to the naked eye, enhancing the experience for those observing the night sky.
In summary, while the Supermoon will brighten the sky and provide a unique viewing opportunity, it should not be seen as an apocalyptic event. Instead, it serves as an excellent chance for astronomical discussion and appreciation.
