By studying comet we can learn about the very first moments of the Solar System , so it ’s very important to have a good idea about their history .
research worker from Western University , Canada used statistical analysis and scientific computing to forge out where 67P / Churyumov - Gerasimenko , AKA Rosetta ’s comet , number from . According to their model , just 10,000 years ago the comet moved from the Kuiper Belt beyond the scope of Neptune to its current location , an off-the-wall orbit between Earth and Jupiter . And 400,000 year ago , its orbit may have direct it beyond Pluto .
This find propose that 67P is part of a group ring the Jupiter - family comets , ones that are strongly influenced by the gas heavyweight . The findings were presented at thejoint forty-eighth annual meetingof the Division for Planetary Sciences ( DPS ) of the American Astronomical Society ( AAS ) and 11th yearly European Planetary Science Congress ( EPSC ) in Pasadena , California .
" These results come from figuring of the comet ’s reach from the present to the past times , which is computationally unmanageable due to the chaosity of the field stimulate by close encounter with Jupiter , " say Mattia Galiazzo in astatement .
" Thus the detail are apart but we can establish a dynamical pathway from its current orbit back to the Kuiper belt . "

The Kuiper Belt is a region of the Solar System that extends from the celestial orbit of Neptune outwards . It is full of asteroids , comet , and several midget planets like Pluto . Most of the little object in this neighborhood have stay on unchanged since the dawn of the Solar System .
This make the finding very interesting . According to Galiazzo and his partner , Paul Wiegert , 67P is made of the primordial textile all the planet in the Solar System come from and it is a recent arrival in the inner Solar System . Before that , the comet spend 1000000 of year in the scattering disk , a distant fortune of the Kuiper belt , before incite inwards after interactions with other objects .
At some tip , the comet ’s path led it too close to Jupiter , which began controlling its arena and trapping it where it is today .
