This Planet Got Exiled From Its Solar System 16 Times Farther Than Pluto

A planet that is located so far from its star, as much as 16 times farther than Pluto from the sun, is apparently kicked out from its original orbit near its parent star, that could also be similar to the early history of our solar system, according to a new study.
Observations and images taken from the Gemini Planet Imager located in Chile and the Hubble Space Telescope reveal that the star also possesses a lopsided comet belt, indicating a disturbing solar system, providing clues how planets were exiled from this system, forcing the comets closer to the star.

Scientists also believe that this exoplanet known as HD 106906 B, may have a ring of debris that was tailing behind it during its expulsion from its original orbit. According to astronomy professor Paul Kalas from the University of California, Berkeley, the planet itself could have attracted some material from this comet belt, surrounding itself with a large dust ring or shroud.
According to Abhi Rajan from the Arizona State University, measurements obtained from this planet also suggest that this planet possesses more dust than others, as the team is continuing to do follow up observations to confirm if the planet is indeed enshrouded by a disc.
These types of planets that are kicked out from their star system are helpful for scientists to gain more insight about the beginnings of our own solar system, since there could be planets that used to belong here other than the eight planets of today.
Kalas says that this could be a picture of our solar system some 13 million years ago, since this can be linked to our own comet belt which is the Kuiper Belt, which also lost this large mass during its evolution. In this new study, observations of young planets like this can provide clues how gravitational disturbances around young stars can kick out many cosmic objects including planets.
This new study is published in The Astrophysical Journal.
