The influence of the sun spreads very widely, as the distance where it stops and starts the gravitational influence of the influence of other stars and the whole mass of our Galaxy. Reliable information about how this is, not yet, although visitors from these spaces from time to time visit the solar neighborhood. Guests – long-period comets, moving in highly elongated orbits.

Where do we come to "tailed stars"? So far, the sources of comets being lively debate, but one decision has not yet been worked out.

Modern observational data on physico-chemical composition of the planets and the comet and asteroid component suggest the next most likely scenario for their formation in the formation of the Sun and the solar system itself.

Thousands of ice chunks break in the inner solar system, representing a serious threat to the planet and, in particular, for the earth. The fall of a large comet or asteroid could cause catastrophic consequences for our planet. According to scientists in the past this happened repeatedly, causing a mass extinction of species.

Using a powerful space telescope, scientists discovered evidence that the water in Earth’s oceans may have been delivered by comets.

Astronomers said that the water and the ocean is on earth came from comets. This analysis result is expressed following the comet Hartley two with Herschel Space Observatory published in the journal Nature on Wednesday (5/10/2011) ago.

Among the data collected by orbiting telescope WISE, the scientists are going to find confirmation of the existence of a hypothetical large planets at the farthest boundaries of the solar system.
