Periodic Comet

Periodic comet attracted by the Sun, sent to him, but pass due to the same sensitivity to the solar wind, which causes the surrounding cloud of dust and gases blown away from the Sun. People believe that the tiny particles of solar wind will impact more than large particles, but this assumption is wrong. If this were so, then how to explain the continued existence of the Asteroid Belt, which includes debris of any size is not affected, apparently, by the solar wind. The small object may lose velocity faster than the larger object because of differences in gravity, but if they are sensitive to solar wind, it occurs the same effect, – they are repelled equally. The comet, which (eventually) reach the Sun, with a very repeatable trajectory around the Sun, losing a lot of water vapor so that the ratio of substances in their composition is aligned at the expense of pushing away by the solar wind. In short, they lose their cover. They fly up with acceleration from the external space, but at this time do not change direction, going outside, and face (with the Sun). In fact, comets complete their orbits, coming nearer in the process, getting closer and closer to the Sun. Continue reading

Comet Catalina

In the new year period in December 2015 on the horizon we can observe the double-tailed comet Catalina C/2013 US10 Catalina.

Comet C/2013 US10 Catalina.

Good news for all lovers of the starry sky — comet C/2013 US10 Catalina two weeks ago passed perihelion, the closest approach to the Sun, and now flies back to the depths of space. Until January 17, Catalina will approach closer and closer to the Ground, and in the first weeks of December, the sky in the middle latitudes it reaches the maximum sky brightness. This is a great chance to watch the comet live — even more so that the next time Catalina will be visible only after a few million years. Continue reading

Solar system

Universe – all existing world, and not having borders in time and space. The earth is one of nine planets that revolve around the sun in very similar orbits on circles. Earth is the third planet from the Sun after mercury and Venus, after Earth comes Mars, ending the inner group of planets . different small size and solid surface. Followed by the giant planets of the outer group . consisting of hydrogen and helium-Jupiter, Saturn, Uranus, Neptune and little Pluto. In the interplanetary space sweep the comets and meteoric bodies. Seven of the nine planets have satellites . they just opened more than 50. The Earth satellite – the Moon is large (fifth largest and first with respect to the mass of the planet) and causing tidal movement, covering the whole Earth from the core to the surface.

The sun and its planets are called Solar system . The diameter of the Solar system 12 billion km from the Sun significantly more Land – in 333 thousand times the mass, and 109 times the diameter. The average distance from the earth to the Sun is 149.6 million km is taken as the astronomical unit to measure distances in the Solar system. Continue reading
