Today (17) is the day the giant moon phenomenon was observed. The star will appear larger and brighter, as it will be at perihelion, which is the closest point in its orbit to Earth. The exact moment of the full moon will vary depending on the time zone. On these clear sky days, it is now possible to see the star and it appears much larger, attracting the attention of everyone who watches it.
accessibility
The satellite will be about 357,364 kilometers from Earth. On average, the Moon is about 384,400 kilometers away from the planet

A full moon occurs when the sun and moon are on opposite sides of the Earth, illuminating 100% of the visible face of the moon.
What is a supermoon?
According to Josina Nascimento, an astronomer at the National Observatory, the term “supermoon” has no scientific basis. It was created by astrologer Richard Noll in 1979 in Dell Horscope magazine, which no longer exists. Noll decided that the term “super” would apply to a full moon that occurs when the moon is at or within 90% of perigee, although the reason for this choice is unclear.
Since it is an unscientific term, there are disagreements among astronomical institutions regarding the distance from the Moon relative to Earth that defines a supermoon.
Josina Nascimento explained that the supermoon can occur during the full or new phase and appear from one to six times a year. However, the distance between the Earth and the Moon can vary, as the Moon's orbit is elliptical rather than circular.
Throughout its orbit, the Moon sometimes gets closer to the Earth and sometimes moves away from it. When it is closest to the Earth, it is called perigee; Already at the farthest point, from the apogee. “Observers may notice a brighter moon than usual. The astronomer added that the phenomenon will be visible in all regions of the world as long as the weather is suitable.
She explained that all full moons rise on the horizon (in the east) when the sun sets (in the west) and disappear in the west when the sun rises, allowing the moon to be seen throughout the night.
date
The first supermoon of 2024 occurred on August 19, when it was about 361,900 kilometers from Earth. The last supermoon of 2024 will be on November 15, when it will be 361,867 kilometers from Earth.
This Thursday's supermoon will be the closest to Earth this year. The size of the Moon is always the same, and there is no increase in the orb in a supermoon. This phenomenon is due to the different angle at which it is observed.
For those who want to enjoy viewing the Earth's natural satellite, it is recommended to stay at points away from urban centres, where the view is more amazing.
