The last supermoon of 2023 will occur this Friday (29th)


The fourth supermoon of the year will occur this week. During the phenomenon, the Moon will be in its full phase and may appear larger and brighter.

The Moon will shine in its full phase this Friday (29th), being considered the fourth supermoon consecutive 2023 and the last one we follow this year. To make the event even more special, know that our natural satellite will be accompanied in the sky by Jupiter and Saturn.



The year’s other Supermoons occurred in July and August. This time, the Moon will reach its closest point to the Earth, called perigee, on Wednesday (27), at 361,552 km from the Earth – on average, the distance between our planet and the Moon that’s 384,400 km.

At 6.37am on Friday (29th), the full phase is reached. On this day the Moon will rise from the east starting at 6.37pm, joining Saturn in the sky. Then it’s Jupiter’s turn to appear, accompanying the duo. The Earth’s natural satellite will remain visible until the following morning.

It’s worth remembering that this won’t be the closest nor the brightest supermoon of the year. These headlines belong to what happened at the end of August: on the 30th of that month our natural satellite was 357,343 km from Earth. In fact, it was also considered a blue Moon.

What is the supermoon?

The name supermoon is an expression coined by astronomer Richard Nolle. Therefore, not being a scientific name, there are some disagreements between astronomical institutions on the distance between the Moon and the Earth which allows us to characterize the phenomenon.

In general, we can consider that a supermoon occurs when the Moon reaches complete phase not the perigee or being close to it. Because it orbits the Earth in a slightly elliptical trajectory, it is sometimes closer to our planet, sometimes further away.

Because of its proximity during the phenomenon, the supermoon may appear 30 percent brighter and 14 percent larger, compared to full phases that did not occur near perigee. It is difficult to notice these differences with the naked eye, but in any case it is worth taking a moment to check out their beauty and even beauty. take photos of the Moon with cameras or smartphones.
