What is Perseid Meteor Shower 2017?
As per space.com, Comet Swift-Tuttle, having a nucleus of about 16 miles (26 kilometers) wide, is the largest object known to repeatedly pass by Earth. The Comet last passed nearby Earth during its orbit around the sun in 1992. It will next pass by the Earth in 2026. In the meantime, Earth will pass through the dust and debris it leaves behind every year, creating the annual Perseid meteor shower. When the term “meteor shower” is used, it actually refers to the pieces of comet debris heat up as they enter the atmosphere and burn up in a bright burst of light. When the debris is in space, they are called “meteoroids,” but when they reach Earth’s atmosphere, they’re designated as “meteors.”
How to see Perseid Meteor Shower 2017?
A skywatcher is advised to go to a dark area and sit outside for a few hours. It may take around 30 minutes for the eyes to adjust to the dark. A rate of 150 meteors per hour means a sight of at least two to three meteors per minute.
Now, THAT’s a meteor shower. The 1833 storm had a profound effect on those that witnessed it; it also gave birth to modern meteor science. Those of us who study meteors dream of such a display happening sometime within our lifetimes.
But it won’t be caused by this year’s Perseid’s.
