Brightest and Biggest Moon in 2010

Just after turning Sun into a ring of fire on 15th January as new moon,
the coming full moon on 30th January night has something in store for
all of us. It will not only shine brighter but will appear bigger as
compared to other full moons during this year. To put it in simple
words - The full Moon of January 30th is the biggest and brightest full
Moon of the year. Is this an illusion or some gimmick played by a TV
channel? No, its something which mother nature has kept in store for
us.

why moon looks bigger or smaller? Things when are faraway look
smaller and when are closer look bigger. So moon at perigee will look
bigger than the rest of the positions of moon in its orbit around the
earth. And if perigee happens within short span of the full moon, it
will look BIG!!!! Try this simple exercise. Hold your thumb very close
to your eye, it will cover all your view and as you move the thumb away
from your eyes, it will appear smaller.

Some full Moons are genuinely larger than others and this coming
Saturday's Moon is quite BIG. Why? The Moon's orbit is an ellipse with
one side 50,000 km closer to Earth than the other. In the
language of astronomy, the two extremes are called "apogee" (far away)
and "perigee" (nearby). On Jan. 30th, the Moon becomes full 3 hours
after reaching perigee, making it around 15% bigger and around 30%
brighter than smallest full Moon we are going to see in rest of the
2010.

so lets don't sit at home on 30th Jan evening, go out and see the bright
shining full Moon, The biggest in 2010.

  1. interesting and logical too since it being the full moon after the annular solar eclipse when the moon was at apogee.it is now 180 deg. opposite and at perigee.the cosmic dramas never end!
