Saturday March 19 we repeat the phenomenon of the lunar perigee: has not happened for 18 years
| |
LONDON - not seen for eighteen years: Saturday, March 19, the Moon will appear to our eyes bigger than usual, 14% to be exact. You will experience what is called "perigee Moon ': the moon, which is full, it will at the minimum distance with Earth, about 356,577 km. What has already been nicknamed the "Superluna," also brought with it the inevitable catastrophic prophecies that circulated a few days with particular insistence on the Net but do not worry: there will be the apocalypse, just a wonderful show astronomical.
PERIGEE - With head held high, and with the naked eye, we witness an astronomical phenomenon very specific, albeit ordinary. But this has not occurred since March 1993. The next full moon, scheduled this Saturday, it will seem bigger and brighter than usual, if the sky is always clear. Our satellite will be perigee, the point of minimum distance from Earth. A phenomenon that depends primarily on changes that periodically affect the lunar orbit, due to the gravitational perturbations exerted by the sun The last lunar perigee occurred in September five years ago. Then, the distance from Earth was 357,210 km. On average, the Earth-Moon distance is 382,900 km. The next peak however, that the maximum distance between the Moon and the Earth, will take place Oct. 12 this year. On that day the satellite will be well over 49,857 km away than it will be Saturday, March 19.
apocalyptic predictions - Coinciding with the "Moon Giant 'on Saturday have emerged from a series of network theory, more or less elaborate, but most apocalyptic. Especially the correlation with the devastating earthquake and tsunami that struck Japan Friday, March 11 is cause for concern for some users not paying attention. Experts, however, astronomers and blogger specializing reassure: "No," Superluna "did not cause the earthquake in Japan," explain on the query, the journal of the Italian Committee for the Investigation of Claims of the Paranormal (the Cicap).
MOON ILLUSION - "The effects of" Superluna "on our planet are low," explains the chief scientist at NASA, Jim Garvin. Stresses that: "Taking into account some very detailed studies of seismologists and volcanologists, the alignment of the Moon in conjunction with the full moon, should not have any major impact on Earth." To enjoy the show the best from the pages American space agency should be observed when the satellite is closer horizon. Furthermore, looking at the moon through a foreground object, such as a tree, is triggered in an optical effect called imaginatively "moon illusion." The human eye is actually deceived and the Moon will appear artificially large.
