So today we will introduce you top 10 fact about Google that you may not know.
The Perseid meteor shower occurs when the Earth crosses the littered path of the 17-mile-wide Comet Swift-Tuttle, which travels in a 133-year-long orbit.
The meteors are called the Perseids because the point from which they appear to hail (called the radiant) lies in the constellation Perseus.
In 2019, Perseid meteor shower will occur on August 12 and 13, when the spectacle peaks.
“Comets are sort of like dirty snowballs: As they travel through the solar system, they leave behind a dusty trail of rocks and ice that lingers in space long after they leave,” the New York Times’s Nicholas St. Fleur once explained. “When Earth passes through these cascades of comet waste, the bits of debris—which can be as small as grains of sand—pierce the sky at such speeds that they burst, creating a celestial fireworks display.”
What is the best time to watch the meteor?
The best time to see the display is between 2am and dawn, wherever you are. We would like to mention that the showers are not as bright in the Southern Hemisphere.
This shower is named for the constellation Perseus, which is where the meteors will appear to originate, but you ought to keep your field of vision as open as possible. Binoculars and telescope are not recommended.
According to Wikipedia “Some Catholics refer to the Perseids as the “tears of Saint Lawrence”, suspended in the sky but returning to earth once a year on August 10, the canonical date of that saint’s martyrdom in 258 AD”.
