What to observe in the sky in August: Perseid meteor shower, five bright planets and two comets for telescope

When it comes to falling
stars, first of all think about the August meteor showers Perseid stream. From July 17 to 24
August, the Earth passes 100 million kilometers in its orbit (the two
one-third of the distance to the Sun), and all the while moving through
a stream of particles left by comet swift-Tuttle.

This year the peak
the intensity of a meteor shower will fall on the night of 11 to 12 August. Zenith hourly number of meteors (ZHR), according to the International meteor organization, can reach up to 100 meteors instead of the average value of 50-70. Plus this year
that night, the maximum intensity will occur in time close to the last quarter of the moon. So
the best time for observing meteors — first half
nights no moon in the sky. The farther you will be able to get away from city light, the better. Optical instrument for observation is required because the field of view, even binoculars, not to mention the telescope is negligible compared to the area of sky that is worth paying attention to.

The smallest
dust particles colliding with the Earth, leave a lasting impression on the observers on the planet’s surface. The Perseid meteors, flying at a speed of approximately 60 kilometres per second, collide with the upper part of the atmosphere at altitudes of about 80 kilometers. When
the observation period of maximum flow we may feel that the traces of meteors come
of the region’s most beautiful constellation of the Northern hemisphere of the sky — the constellation Perseus. You will find it in the northeast, focusing on the famous constellation of Cassiopeia.
