Full Moons vary in size because of the oval shape of the Moon's orbit.
The Moon follows an elliptical path around Earth with one side ("perigee") about 50,000 km closer than the other ("apogee").
Full Moons that occur on the perigee side of the Moon's orbit seem extra big and bright.
Basically, I think, because of the oval shape of the Moon's orbit, it will be closer to us as well as being lined up with earth and sun...I think.
Regardless, the moon tonight should be spectacular.
