Last night could enjoy at first sight, an amazing sight, popular meteor shower Perseids
Though still be seen until August 24, peaked yesterday; and as the moon was waning phase was not an obstacle for observation, so we could enjoy up to 120 shooting stars per hour. And the best thing that could be seen with the naked eye without a telescope.
Small dust particles
Calls shooting stars are actually small particles dust of various sizes, some smaller than grains of sand, that leave the comet along its orbit around the sun.
When a comet approaches the inner regions of the solar system, its core, It consists of ice and rock, is sublimated by the action of solar radiation and generates the characteristics tails of dust and gas.
The current resulting particles are dispersed by the comet’s orbit and is crossed every year by Earth on its journey around the sun.
During this meeting, the dust particles disintegrate rapidly upon entering the Earth’s atmosphere, creating light trails known receiving the scientific name of meteors.
Tears of St. Lawrence
The name Perseids, although Spain also known as the “Tears of St. Lawrence” by the feast of the saint, It is because the area of the sky where they seem to leave meteors by a perspective effect (heating), is in the constellation Perseus.
Its popularity is due in part to its activity, the more intense, and partly produced in August, the month that summer, away from city lights, you can enjoy more of the night sky by the warm temperatures.
The Perseids have their -meteoroides- origin in small fragments detached from the periodic comet 109P / Swift-Tuttle, which goes around the sun every 130 years.
The Perseids have been observed for centuries but were officially recognized in the mid- nineteenth century and is one of the best studied rains.
The Perseid meteoroids hit our atmosphere at 59 kilometers per second-much faster than the Geminids, which make a 35- making them meteors fast and bright.
However, their sizes are small, as the Perseid meteoroids that cause intermediate brightness are a few millimeters in diameter and producing the cars (very bright meteors) just a few centimeters . width
