Astro-Image of the Day: Moon at its biggest of the year for 2009 on Saturday

Remember last month's post about the Moon being at perigee, its closest to the Earth? Well, it's about to happen again this month: Two perigee full Moons in two months! Wow!

Click the image to see the story.

A perigee Moon appears 14% wider and 30% brighter than a normal full Moon, so if it's been seeming really big and bright while waxing over the last week, that's because it has been growing in size from our perspective. (No, Virginia, it doesn't actually gain mass or volume. It's just closer, and closer looks bigger.) And you know that cool thing where the Moon looks huge as it rises from objects along the horizon? Well, it'll appear even more bigger-er!

Enjoy! If it's clear, I'll try to take some new astrophotos through my 'scope.
