May 6, 2012 Perigee - tonight’s moon really is at its closest.
Astronomers call this sort of close full moon a perigee full moon. The word perigee describes the moon's closest point to Earth for a given month.
At perigee, the moon lies only 356,955 kilometers (221,802 miles) away. Later this month, on May 19, the moon will swing out to apogee - its farthest point for the month
- at 406,448 kilometers (252,555 miles) distant.
Perigee full moons bring the highest (and lowest) tides of all.
The mornings of May 5 and 6, 2012 are probably best for meteor-watching.
