The Moon Looks Bigger Tonight
Put your coat on tonight and go outside to see a natural wonder that happens infrequently in our lifetime. The moon will look bigger and brighter tonight than it has appeared in fifteen years.
The Moon travels in an oval orbit around the Earth, and tonight it happens to line up at its closest point in 15 years, along with being a full moon to boot. That means the moon will appear 14% bigger and 30% brighter (along with making high-tide a bit higher). This won't happen again until 2016.
And it coincides with the annual Geminid meteor shower.
