Perseids 2015: New Moon and the “Jupiter Effect” reinforce the Shooting Stars – GISMETEO.Novosti

This year add up ideal conditions for observing the Perseids. First, the peak of the meteor shower (August 12-13) is for the new moon. Secondly, the influence of Jupiter increases the number of meteors.

The Perseids are pieces of the comet Swift – Tuttle, which passed the sun in 1992 and will return next time in 2126. Trailing behind the comet tail has an elliptical shape. Every year in mid-August the Earth crosses it almost at a right angle.

The particles that create the “Shooting Stars” is very small – about the size of the large grains of sand to small pebbles. Entry into the Earth’s atmosphere at a speed of 60 km / sec, they immediately burned, leaving a dark sky glowing tracer. This occurs in the layer from 112 to 64 km.

Left comet meteor trail also passes close to the other planets. The most significant influence on him has Jupiter. Despite the fact that the comet meets him with 11.8-year period (as long it takes Jupiter to orbit around the Sun), and flies at a distance of 257 million kilometers, powerful gas giant’s gravity enough to push the tail of a comet to Earth.

As a result, the number of meteors increases. Normal flow rate of 90 per hour.

The last time the comet Swift – Toutle held “near” Jupiter in November 2014. This means that for 22 months the comet’s tail will be located close to the Earth’s orbit. Thus, the next – in 2016 – the year also includes a bright stellar show.
