Jupiter for 12 years of keeping comet

In the middle of last century, Jupiter took a passing comet, which released 12 years later. Data presented at the European Planetary Congress in Potsdam (Germany), show that the largest planet in the solar system in the years 1949-1961 had a temporary satellite, which was a comet 147P/Kushida-Muramatsu. This is the fifth such incident known. Comets - lonely wanderers. Sometimes they need a century to fly around the sun. In rare cases, however, these mysterious formation of ice and dust can take place in the immediate vicinity of the planet, and that's when they come to the gravitational attraction. Sometimes it ends with a heavenly body falls and breaks on the planet, as the comet Shoemaker - Levy 9 fragments of which crashed into Jupiter in 1994. Most of the observed phenomena do not result in the temporary seizure of the fact that the comet makes a full circled the planet. Meanwhile, according to calculations Katsuhito Otsuki of Tokyo meteor Service (Tokyo Meteor Network), the comet Kusidy - Muramatsu twice flew around Jupiter in irregular orbit, before once again gained freedom. "Our results show that the fall of comets at Jupiter and the temporary seizure may occur more frequently than we expected", - said David Asher of Armagh Observatory in Northern Ireland, speaking in Potsdam. This finding is relevant to assessing the risk of collision of a comet with the Earth - an event that would have catastrophic consequences. Some scientists believe that the fall of an asteroid or comet on Earth ended the long reign of the dinosaurs about 65 million years ago. Jupiter is often seen as a "keeper", which catches a comet that could threaten Earth. He can also knock them off course, affecting circumsolar orbit of comets.
