The Moon’s distance from the Earth is
not always the same due to the elliptical shape of the orbit
and variations in the gravitational attraction between the Moon,
Earth and Sun.
When a full moon occurs close to the
perigee of the
Moon (a point of its closest approach to the Earth) and its
distance from our planet is much smaller than the usual one, then we
can observe a “super moon” phenomenon.
Although every year there is from 4 to 6 super moons, not
all are the same powerful, neither by the intensity nor by the duration
of their effect. It has caused many discussions in scientific
circles about the full moon on May 6, 2012 which is
going to be one of the most powerful in years. |
