Be ready on Supermoon

Be ready, on December 3, 2017 to come, we can all witness the first full supermoon and the last time this year. Supermoon is a popular term for the full moon that coincides with the moon that reaches the moon's closest distance to the earth. The moon's orbit that surrounds the earth itself is not a circle, but an oval shape.

That is, the distance of the moon to the earth varies, sometimes reaching the nearest point (perigee) and other times are at the furthest point (apogee). Technically, this will be the fourth supermoon of the year. But what is seen on December 3, 2017 will be the only thing that can be seen with the naked eye. This is because three previous supermoon coincide with the new moon phase.

Throughout the night, the moon will appear 7 percent larger and 16 percent brighter than usual. Of course not easy to distinguish it from the naked eye. But the best time to enjoy the view will be like a full moon in general, which is a few minutes after sunset. At that time, the optical effect called the illusion of the moon will make the supermoon appear much larger and brighter than usual.

Sky observers in northern Alaska, Canada, Russia, and parts of China are even lucky to see the moon slide briefly in front of the star. Although it does not require special tools to see this phenomenon, if you use a camera with a telephoto lens, telescope, or binoculars, there will be a better chance of seeing the surface of the moon. If your area is cloudy, do not worry, you can watch it online. Astronomers will provide real-time images of the beautiful satellite over the legendary monument of Rome, Italy.

Even if you overslept and did not have time to watch it, no need to be disappointed, because there will be two supermoon early next year. Precisely on January 2 and 31, 2018. But for now, let's hope December 3, 2017 night will be bright!
