sun & moon & stars

From Smithsonian:

This weekend, the Moon will become a Supermoon. And not only that, but this Saturday’s Supermoon will be the most Supermoon-y Supermoon to Supermoon all year. The distance of the Earth to the Moon varies over time. Throughout 2013 the Moon will travel in and out by 30757 miles, around 13% of the average Earth—Moon distance. A Supermoon is a full moon that takes place when the Moon is within the nearest 10% of this drift, and Saturday’s Supermoon will be the nearest-approaching Supermoon all year.
