Combustion up to 100 «stars» an hour will be able to see the inhabitants of the Earth in the night from Sunday to Monday due to the upcoming high of the bright meteor shower, the Perseids.

«In Moscow the night of Perseid maximum from 12 to 13 August will be moonless. The young Crescent moon will disappear behind the horizon after 21.00 GMT and will be at 7.30 am GMT. To prevent can only clear. According to the International meteor organization (IMO) is expected to be 100 meteors per hour,» say the astronomers of the Moscow planetarium.

How to watch the Perseid

Enjoy the sight of «shooting stars» will be possible in the absence of clouds: the Moon on August 11 has passed the phase of new moon, so its light will not interfere. To see the Perseids can not only astronomers, but also ordinary observers around the world. The meteors are bright, but they need to observe away from city lights, creating a so-called «stray light», and then have the chance to see many of the weaker meteors.

Observation does not require telescopes and other astronomical instruments. To monitor better than in nature, for example, in the field, in the country or in the village. However cloud and rain may interfere even there. It is believed that meteor showers are a very beneficial effect on the human energy.

Make a wish

While stargazing, it is customary to make wishes. «Star rain» from the constellation of Perseus is poured on the Ground in the period from 17 July to 24 August and reaches its maximum in the night from 11 to 13 August, then you can enjoy the most popular and the bright star of the year in all its glory. Meteor showers are shed every year because the Earth’s orbit and flow have a constant area of intersection with each other. The activity of the Perseids from year to year irregular activity bursts weakens with increasing distance between the comet and Earth.

In normal years, a meteor shower is relatively removed from the Earth’s orbit and outside it. Periodic convergence of cometary tracks with the Ground accompanied by increased activity of Perseids. Last time this happened in 2004 and 2009. Following bursts of activity flow is expected in 2028, said the Moscow planetarium.

As he opened the Perseids

The name Perseids comes from the constellation of Perseus. Perseid meteor shower known to mankind for about 2 thousand years. The first mention of them are found in Chinese historical annals dated 36 ad. Also the Perseids was mentioned frequently in the Japanese and Korean Chronicles VIII-XI centuries. In Europe, the Perseids were called «Tears of St. Lawrence», as the festival of St. Lawrence, which takes place in Italy, falls on the peak of the meteor shower — on August 10.

Officially, the discoverer of the annual meteor shower Perseid is a Belgian mathematician, astronomer, meteorologist Adolf Ketele, who reported about this show in August 1835. For the first time the number of meteors flashing during each hour, calculated in 1839, and the maximum number of meteors per hour then up to 160.

To see the comet’s tail

The Perseids are the result of the passage of the Earth through the plume of dust particles released comet swift-tuttle. The smallest particles, the size of a grain of sand, burn up in earth’s atmosphere, forming a star rain. First, he «poured» with the greatest force, then gradually weakens. Perseids — white meteors, and sharply scribe marking the sky. The glow of some particularly bright meteors lasts a few seconds.

During the summer of 1862 appeared in the sky beautiful and previously unknown to astronomers, the comet. It opened on 16 July 1862 by American scientists Lewis swift and Horace Tuttle. The comet was named — comet 109Р/swift-tuttle. The rest of the summer of 1862 in the Northern hemisphere of the Earth, this comet was visible high in the sky. And in the last week of August, the comet reached a maximum magnitude, the second magnitude, also had a bright long tail.

When observing the comet through a telescope could be seen glowing misty wisps radiating from the dense core of the comet, like the petals of a flower. Not accidentally, the great popularizer of astronomy Camille Flammarion put the comet swift-tuttle in the top ten most beautiful comets of the nineteenth century. Others called it simply — the Great comet of 1862.

Comet swift-tuttle is a large comet — its nucleus has 26 kilometers (16 miles) in diameter, more than twice the size of the intended object to fall that led to the death of the dinosaurs. With its appearance, the researchers drew attention to the connection between comets and meteor streams.

In 1867, the famous Italian astronomer Giovanni Schiaparelli announced that the orbit of the comet swift-tuttle almost coincides with the orbit of the Perseids and the comet threw himself from tiny fragments of particles that give rise to the Perseids, when Earth passes through them. Giovanni Schiaparelli was the first to realize that the source of the Perseids is comet. Today found that the majority of meteor showers associated with the remains of comets.

The orbital period of the comet swift-tuttle is about 133 years, now it moves to the outer limits of the Solar system. Every possible approach to our sun makes its orbit a new batch of cometary grains. Accordingly, coming to this event pleasing to terrestrial observers a sharp increase in the number of «shooting stars». The last time the comet swift-tuttle passed near the Sun in December 1992, and will return to it again only in July 2126. So for several years close to 1992, the Perseids were very active. For example, in August 1993, observers in Central Europe recorded from 200 to 500 meteors per hour.
