Let’s look at the sky: rain the Perseids – The Tribuno.com.ar

August 10, 2016 – 1:30 This week begins one of the most famous star rains: the Perseids. And the you can see very well.

Every year, between late July and late August, Earth crosses his path around the Sun in the wake of Comet Swift-Tuttle, which causes many particles, called meteoroids, crashing into the atmosphere. As the Earth goes deeper into this cloud of meteoroids, Perseid activity increases.
Are so well known that in the Chinese annals of 36 A.D. and we find references. Have extensive meteoric curriculum.
Called “shooting stars” are actually small dust particles of different sizes, some smaller than grains of sand that are leaving comets or asteroids along their orbits around the Sun. . the resulting cloud of particles (called meteoroids), due to melting caused by solar heat is dispersed by the comet’s orbit and is crossed every year by our planet in its orbit around the sun.
During this meeting, dust particles disintegrate rapidly upon entering the Earth’s atmosphere, creating luminous strokes known receiving the scientific name of meteors.
perspective effect, all trajectories of different fleeting stars converge to a point called the radiant sky. The constellation in which the radiant is located gives its name to the rain. Thus, the Perseid radiant is located in Perseus, while for the Geminids will be in Gemini.
Most meteoroids detached from Swift Tuttle
are as small as a grain of sand, and when intersect impact our planet’s atmosphere at a speed of more than 210,000 kilometers per hour, equivalent to explore the country from north to south in less than twenty seconds.
the crash occurs in these fragments, an increase of temperature of up to five thousand degrees in a split second, which makes disintegrate and emit a flash of light called a meteor or shooting star.
This decay it occurs at high altitude, usually between one hundred and eighty kilometers above the ground. Larger particles (the size of a pea or larger) can produce much brighter shooting stars are called fireballs.
Just hope that this month Salta sky is clean and allow us to see this show.
