Saturday Night Special : Biggest Full Moon of 2009
If skies are clear Saturday, go out at sunset and look for the giant moon rising in the east. It will be the biggest and brightest one of 2009, sure to wow even seasoned observers.
Earth, the moon and the sun are all bound together by gravity, which keeps us going around the sun and keeps the moon going around us as it goes through phases. The moon makes a trip around Earth every 29.5 days.
But the orbit is not a perfect circle. One portion is about 31,000 miles (50,000 km) closer to our planet than the farthest part, so the moon’s apparent size in the sky changes. Saturday night (Jan. 10) the moon will be at perigee, the closest point to us on this orbit.
It will appear about 14 percent bigger in our sky and 30 percent brighter than some other full moons during 2009, according to . (A similar setup occurred in December, making that month’s the largest of 2008.)
Tides will be higher, too. Earth’s oceans are pulled by the gravity of the moon and the sun. So when the moon is closer, tides are pulled higher. Scientists call these perigean tides, because they occur when the moon is at or near perigee. (The farthest point on the is called apogee.)
This month’s full moon is known as the Wolf Moon from Native American folklore. The full moon’s of each month are named. January’s is also known as the Old Moon and the Snow Moon
