The supermoon term has reached the full moon the same day the moon is in the perigee, or its closest passage to Earth in its monthly path around the sun.
The astronomer who invented the term supermoon uses this term in reference to the new moons and full moons that are produced near the perigee. That said, there has been very little interest in the “super new moons” because you can not see a new moon. Mahalo at the Bishop Museum Planetarium for this climax of astronomy.
Two supermoon events had already taken place in 2019, one in January and one in February. Thursday’s event will be the last of the year. We will not see this phenomenon again for 11 months, the next one in February 2020.
What is a supermoon
A supermoon occurs when the full moon appears exceptionally large in the night sky. For this to happen, the conditions must be almost perfect with clear skies. It must be a full moon and the moon must be closer to Earth.
Distance between the Moon and Earth
The distance between the Moon and Earth is approximately 360,000 kilometers and will be more than 99% illuminated. By way of comparison, the average distance between the Moon and the Earth is about 384,000 km and the farthest distance the moon draws from the Earth is about 405,000 km.
According to the average three supermoon events per year, it is clear that being able to attend one of them is a very special occasion. Of course, you would like to capture the moment and post it on your Instagram, right?
Taking a picture of the supermoon is going to be challenging
Ttaking a picture of the super moon with your smartphone will be very difficult. One because there is not much light. Two, even closer to Earth, the moon is still so far that you will need a very good zoom to capture the details and three, you will need to have the camera mounted on a tripod to be able to take a clear and clear picture.
