SuperMoon : Closest to The Earth

Info Pasal Super Moon ni aku dapat tau dari Blogger JoeGrimmjo (btol ke salah eja ni?), dan aku pasal Astronomi ni menarik minat gak, rasanya prefer tulis in english kot... For International Reading gitu...so, may i proceed about this SuperMoon?

These day, Universe seems try to reveal some sort of their a bit secret. Last Year, if i may recalled, i do wrote about 'Eclipse' (Moon and Sun Eclipse), and now this Supermoon catch my interest to dig a bit about the amazing universe! This story that i would like to share from News@Yahoo where i think they got few detail that i can relate to this post.

Since i blogged about 3 years now, there were few entries about Universe in my blog related to The Moon and The Sun. Before i related to my previous entries, let me tell you a bit from News@Yahoo about SUPERMOON that will be happen on 19th March 2011! Once in 18 Years!!

"'Supermoon' is a situation when the moon is slightly closer to Earth in its orbit than on average, and this effect is most noticeable when it occurs at the same time as a full moon," Garvin wrote in the NASA statement. "So, the moon may seem bigger although the difference in its distance from Earth is only a few percent at such times." [Photos: Our Changing Moon]

The full moon of March will occur next Saturday on March 19, when the moon will be about 221,567 miles (356,577 kilometers) away from Earth. The average distance between the Earth and the moon is about 238.000 miles (382.900 km).
"It is called a supermoon because this is a very noticeable alignment that at first glance would seem to have an effect," Garvin explained. "The 'super' in supermoon is really just the appearance of being closer, but unless we were measuring the Earth-Moon distance by laser rangefinders (as we do to track the LRO [Lunar Reconnaissance Orbiter] spacecraft in low lunar orbit and to watch the Earth-Moon distance over years), there is really no difference."

It was astrologer Richard Nolle who linked the full moon of March 19 to natural disasters. He claimed that this "supermoon" would trigger massive earthquakes, volcanoes and powerful storms when it arrived.  But scientists assure that this is not the case. ['Supermoon' Did Not Cause Japan Earthquake and Tsunami]
 So, The Moon will be 26, 323 KM much closer to The Earth! Please read some explanation about to NOT related The Disaster happened in Japan to this SuperMoon! Maybe it just a coincident.

"The effects on Earth from a supermoon are minor, and according to the most detailed studies by terrestrial seismologists and volcanologists, the combination of the moon being at its closest to Earth in its orbit, and being in its 'full moon' configuration (relative to the Earth and sun), should not affect the internal energy balance of the Earth since there are lunar tides every day," Garvin wrote.

But while the moon helps drive Earth's tides, it is not capable of triggering devastating earthquakes.
"The Earth has stored a tremendous amount of internal energy within its thin outer shell or crust, and the small differences in the tidal forces exerted by the moon (and sun) are not enough to fundamentally overcome the much larger forces within the planet due to convection (and other aspects of the internal energy balance that drives plate tectonics)," Garvin explained.

p/s: pardon my English..need more improvement and practice.
