What are perseids?
Perseids are the regular and most predictable meteor shower which appear regularly every year. They are associated with Swift Tuttle comet and appear to rise from the radiant in the constellation Perseus. Swift Tuttle comet, formerly known as 109P, travels toward Earth’s part of solar system every 133 years leaving traces of perseids. It was last seen in 1992 after its discovery year 1862 AD. Next time Swift Tuttle is predicted to be seen in 2126 AD. Perseids, formed by motion of Swift Tuttle, are active from mid-July to end of August every calendar year and meet their peak shine in between 9th August to 14th August. This period produces beautiful sights for stargazers. In 2013, the peak was seen on 12th August. In 2014 too, they are expected to shine most visibly around 11-12th August. Perseids appear and disappear from human being’s achievement at a height of about 50 miles from the Earth surface.
Perseids vs Full Moon (supermoon)
As 10th August had full moon and perseids are appearing in the same period, it would be interesting how sky will look this time. Science at NASA has an illustrative analysis of this event, last time happened similarly in 2011.
The meteor showers of 2012 and 2013 were recorded in these time lapse YouTube videos:
