Discover the missing link of comet origin

An international team of scientists, including astronomer Brett Gladman from the University of British Columbia, has found a strange object whose reverse and tilting trajectory may shed light on the origin of the comet.

In the first discovery of this field, researchers from Canada, France and the United States discovered an object that has an orbital rotation of the Sun and tilted at an angle of 104 degrees - almost perpendicular to orbit fine in the system.

"Such comets are not naturally formed after the formation of the planet, especially with comets with high inclines," Professor Gladman said. This finding could eventually show how they moved from the Oort (Oort Cloud) cloud - known as a comet cloud - to become Halley comet-like objects.

The material is mainly ice-shaped rock, 2008 KV42 is called a "trans-Neptunian" because its orbit is bigger than Hai Vuong Tinh's orbit. This object has a rough width of about 50 kilometers and is currently 35 times farther away from the Earth and the Sun.

The trajectory of such objects in the region that is beyond Neptune's orbit limits provides insightful and clear information about the early days of our solar system, Gladman said, he is lecturer in physics and astronomy and is the president of Canada's research in Planetary Planetary Astronomy.

This international group has just made a search for objects with large tilting trajectories. This new discovery is made through the Canada-France-Hawaii telescope located in Hawaii with follow-up observations provided by MMT glasses in Arizona, Cerro Tololo Inter-American observatory glass (CTIO) at Chi. -lê and Germini South are also in Chile.

"Having a quick access to MMT and Germini South glasses is crucial, through the enthusiastic help of observers and executives. With such unusual trajectories, we could lose track if there is no quick follow-up from such large telescopes. "

The group is currently conducting follow-up observations on 2008 KV42 to monitor its trajectory with greater accuracy. Then they will begin to clarify the information behind this other injured object.
