Continuing our top 10 ranges, today we will write about top 10 largest cities in the world by land area.
The biggest full moon of 2012 is due to arrive this weekend. The moon will officially become
full on May 5 at 11:35 p.m. EDT. And because this month’s full moon coincides with the moon’s perigee, its closest approach to Earth, it will also be the year’s biggest. The moon will swing in 221,802 miles (356,955 kilometers) from our planet. Аccording to meteorologist Joe Rao and not only does the moon’s perigee coincide with full moon this month, but this perigee will be the nearest to Earth of any this year, as the distance of the moon’s close approach varies by about 3 percent. This happens because the moon’s orbit is not perfectly circular. This month’s full moon is due to be about 16 percent brighter than average. In contrast, later this year on November 28, the full moon will coincide with apogee, the moon’s farthest approach, offering a particularly small and dim full moon. Though the unusual appearance of this month’s full moon may be surprising to some, there’s no reason for alarm. The slight distance difference isn’t enough to cause any earthquakes or extreme tidal effects, experts say. However, the normal tides around the world will be particularly high and low. At perigee, the moon will exert about 42 percent more tidal force than it will during its next apogee two weeks later. To view this weekend’s supermoon to best effect, look for it just after it rises or before it sets, when it is close to the horizon. There, you can catch a view of the moon behind buildings or trees, an effect which produces an optical illusion, making the moon seem even larger than it really is.
