On the last day of August, the ‘Super Blue Moon’ rises. It is a rare astronomical 먹튀검증phenomenon that occurs at the same time as a ‘supermoon’, when the moon approaches the earth and appears large, and a ‘blue moon’, when the full moon rises twice in a month. It will happen in 5 years since 2018, and if you miss this opportunity, you will have to commit to 14 years later.
On the 20th, the Gwacheon National Science Museum announced that it would hold a special Super Blue Moon observation meeting on the 31st.
A supermoon is a full moon that occurs when the moon is at perigee, the closest point to the earth. The moon orbits the earth in an elliptical shape. Because of this, it is said that it moved away from the earth and then came closer. The closest is 350,000 km , and the farthest is about 400,000 km . The supermoon on the 30th is analyzed to be 357,344 km from the earth to the moon. It is the closest to Earth among the full moons of this year.
Because of this, the full moon appears rounder and larger. The Moon is 14% larger and up to 30% brighter than at its smallest size. However, atmospheric conditions and subjective factors also play a role in making the moon appear larger, so you may not notice a special difference with the naked eye.
The word supermoon is not scientifically defined. The term supermoon was coined by American astrologer Richard Knoll in 1979. The astrology magazine ‘Del Horoscope’ wrote the word supermoon and defined it as ‘a new moon or full moon that has approached 90% of the Earth’s perigee.’ Its official astronomical name is perigee.
What makes this Supermoon even more special is that it overlaps with the Blue Moon phenomenon. The moon phase changes every 29.5 days, with a difference of about 11 days per year. Because of this, every two years and eight months, the full moon rises once a month. The second full moon in a month is called a blue moon. In the West, the full moon is seen as a symbol of bad luck, but when the full moon rises twice in a month, it is called a blue moon because it is gloomy and ominous
. The most recent occurred on January 31, 2018. The next occurrence is 14 years later, on January 31, 2037.
The Gwacheon National Science Museum runs lectures, observations, and experience programs related to the Super Blue Moon from 7:00 pm to 9:30 pm on the 31st. Han Hyeong-joo, director of the Gwacheon National Science Museum, said, “If you miss this Super Blue Moon, it is a rare astronomical phenomenon that you will have to wait 14 years for.” More information about the event can be found on the Science Museum website.
