Comets threaten to arrange in the Solar system chaos
If the Sun will increase its luminosity by a few percent, the ice will begin to evaporate and jets of gas will give the comets the reactive acceleration.
“Graveyard of comets”, are found in the asteroid belt between the orbits of Mars and Jupiter, can make a real chaos in the Solar system when the Sun will Shine a little brighter. Astronomers can’t predict which direction will fly the heavenly bodies, when their trajectories change .
“We found a graveyard of comets. Imagine all these asteroids within the belt orbit the Sun for millions of years and show no signs of activity. We found that the majority of them are “dormant” comets that may yet come back to life if their solar “energopac” will be increased by couple of percent,” says Ignazio Ferrini of the University of Medellin (Colombia).
Previously it was thought that most comets in the Solar system is in the so-called Kuiper belt beyond the orbit of Neptune. However, it was discovered that several hundred dormant in the asteroid belt, moving in relatively stable orbits between Mars and Jupiter. Since they don’t show their tails and not move on watanasiritham, the scientists called their gathering the “graveyard of comets”.
However, the new mathematical model allowed the astronomers to realize that if the Sun increases its luminosity by a few percent, the ice comet in the asteroid belt will begin to evaporate and jets of gas will give the comets the reactive acceleration, unpredictable, changing the trajectory of their movement. Flight of influencing each other, they will tangle their trajectories, and in the Solar system into chaos.
In his article, published in the journal of the Royal astronomical society of great Britain, Ferrini recalled the discovery in the last in the asteroid belt of 12 active comets that have warmed up to such an extent that they have cometary tails. The evaporating gas has already begun to affect their trajectory, gradually pushing with a stable orbit.
We will remind, the brightest comet of the decade, opened in September last year by Russian astronomers, will fly at 62 million km from Earth on 26 October 2013. This is less than half the distance from the Earth to the Sun. Some experts fear a possible threat, which can carry a comet. Supporters of the opposite opinion refer to the distance – though it would be less than from the earth to the Sun, but it’s still far enough to not be afraid of a collision or any other impact on our planet.
